Gemcraft Labyrinth Walkthrough: Combining & Using Gems

Learning How to Combine Gem's in the third game is as essential as it has ever been

Combine Gems (G) – merges two gems to combine abilities, combine two gems of the same grade to increase gem’s grade level.

In order to succeed against powerfully enemies, you will need to have access to powerful gems. While it is certainly cheaper to create gems, combining gems is the only way for players to utilize lower grade gems that have been utilized for the initial waves, and more importantly, combining is the only method that allows a player to create a gem with multiple abilities. To combine, you will need to have two gems and enough mana for the creation of a grade 1 gem (this is the basis for the casting cost of combination, and like gem creation this mana cost is affected by the forge skill). There are two different factors that players should remember when combining gems: the grade and color of the gems being fused.

You can combine any gem in the field and in your inventory. This means you can grab gems on traps, towers, amplifiers and the inventory then merge them with other gems from the same sources. Gems merged in the inventory or in amplifiers will be ready for action immediately. Gems in traps and towers will go through a cooldown cycle before it is ready to function. Since combining gems is a long and tricky process –particularly with multi-color gems (as you will need to read the stats carefully), we highly suggest that players first pause the game before starting this.

When you combine gems of different grades, the result will always be a gem of the same level as the higher grade ingredient. Combining two gems of the same grade will result in a gem of a higher grade. For example, you combine a grade 2 and a grade 3 gem. The fused gem will be a grade 3 gem. This gem will have slightly increased stats as a bonus from the combination. Combining gems of the same grade however, will result in a gem with a grade level that is 1 tier higher than the ingredients. Hence, combining two grade 4 gems will give you a grade 5 gem.

Aside from grade levels, the gem’s colors also affect the abilities it has. As you may have noticed, gems of different colors will have different abilities. Combining two gems of the same color will always wield a same color gem with slightly higher stats and improved ability stats. Combining two gems of different colors on the other hand will have an additional bonus to base damage, has a faster firing speed, has a longer range (as compared to the base stats of the two gems) and best of all, compounded abilities. This means that if you combine a poisonous gem with a mana gathering gem, you will get a dual color gem that will poison your enemies and gather mana with each hit. Impressive right, you can even add more gems to the mix further increasing the bonuses and more importantly, the number of effects that the gem will have.

Combining however, it does come with a slight drawback. Multiple abilities will be present, but they will be slightly weaker as compared to their stats on pure gems. Pure slow gems will always have a longer effect duration on enemies as compared to a multi color gem with the slow ability.

When combining two gems, there is no such thing as a base component. So it really does not matter which gem you grab first in the combination procedure. The only things that matter are the gem’s colors and grade levels.

Remember, combining gems is a major part of the game. In fact, it is practically impossible to win the game using low level gems throughout –even on the most basic stages. You will need at to reach at least a grade 3 gem to finish the simplest end-stage waves. For the rest of the game’s fields, you will find yourself crafting gems that will cost several tens of thousands just to create in order to win.

Lastly, once you have come up with a great gem creation, be it pure or multi-color, remember to use the anvil’s duplicate function in case you need another. Combining gems is always more expensive than creating one directly.

Throw Gem Bomb (B) – attack monsters, destroy structures, destroy nests, increase wave volume, use on gem anvil for mana gain.

The gem bomb is a versatile and powerful tool –provided that players know how to use it. Activating this ability is simple, pause the game, then simply click on the gem bomb tool icon or press B, then select a gem and drag that gem to the target. Alternatively, you may choose to pause, grab a gem, and then press B before releasing the gem on your target area. The important thing here is to pause. This is the most crucial step before you activate gem bomb on anything. If you accidentally miss your target with a gem bomb, you risk losing the gem you are holding and you may accidentally hit something you did not mean to (like destroying a tower or increasing the volume of the wrong monster wave tile). Also, monsters tend to move quite fast, so if you want to accurate hit a certain group of monsters with the gem bomb, pausing the game is your best bet.

There is no mana needed for activating gem bombs –the fact that you will sacrifice a gem permanently is a big enough cost. What you do need, however, is the knowledge of how a gem bomb will affect what you drop it on. As the name implies, this is a bomb and as such, it has destructive properties against both monsters and structures.

As a weapon against monsters and structures with HP, the gem bomb’s destructive property relies on the grade level of the gem being used. When used against your own structures (traps, walls, towers, amplifiers), a single grade 1 gem is more than enough to demolish those. Note that shrines cannot be destroyed and will not be affected by the gem bomb. When attacking monsters, gem bombs will have a small destructive range, so make sure you maximize this by waiting for enemy monsters to cluster around your target.

A more interesting use of the gem bomb is for increasing the volume of enemies you will be facing in a specific wave. As you may have noticed, the monster wave tiles on the left side of the screen determine how long it will take for the next wave to arrive. You can also highlight the tiles to see a general overview of the kinds of monsters you will be facing. If you see a wave with stats that you can easily handle, you could hit it with a gem bomb to boost the number of monster that will pop out. But remember, waves will overlap, so also check the waves before and after your target tile (the last thing you want is to be handling a boosted wave of armored baddies while a swarm wave tile is coming up next). Gem bombing a title is a great way to boost mana earnings during the first few waves when enemies are easy to handle, or after you have already managed to create a solid base defense. You can also gem bomb a title several times, though be sure to do this with caution, doing so repeatedly may result in an over congested wave that will run you over.

The last application of the gem bomb is to drag it over the gem anvil for a quick mana refund. This is our least favorite function and so far, we have only three practical uses for it: the first is for correcting mistakes –this means trying to get a small refund out of gem you accidentally created (wrong color, wrong grade level, anything). But as opposed to getting a refund, it is still far more acceptable to just fuse a wrong gem with an existing gem (use it as a stat boost). The second use is for gaining an extra bit of mana when you really need it (like for creating a tower or trap near the base as a last minute effort). The third, and only tactical use, is when you have finally unlocked the wild gem ability. The wild gem ability will spawn a gem in your inventory at the very start of the match. Since this gem is completely free, you could sacrifice it for raw mana –which you may then allocate for building structures or for another gem of a color you prefer.

Gem Anvil – duplicates gems (D), extracts mana (X), clones and upgrades (U)

The gem anvil is your best friend when it comes to crafting special gems. With the auto-clone/combine feature, the anvil will save you precious time when clicking around the screen. With the duplicate function, it saves you those preciously limited mana points. Lastly, it has an extract mana feature –which, though entirely all that practical, is actually a big help for new players who make plenty of mistakes.

Our main use of the anvil is for it to duplicate gems. This is not much of a big deal when you are dealing with basic pure gems –after all, you can create those normally. But if you have gems that have been boosted through a lower grade combination (like combining a grade 1 and a grade 2 bloodbound gem), getting a second one just like it will be expensive through direct crafting. The anvil on the other hand will save you the mana that you would spend in combining and in the cost of creating two different gems. Just drag the gem you want to clone and place it on the anvil (or just press D and click on the gem), this will give you the gem you want. Naturally this works for multi color gems as well (since making those normally means spending plenty of mana on several gems just to create a single end product).

With the duplicate function alone, the anvil already gives plenty of help to players. But what makes it even more enjoyable to use is its clone and combine feature. Okay, this one is really more of a convenience than anything else. What it does is it will automatically duplicate a gem then merge the original with the clone to create an upgraded version of the original gem. Since this is often the end-goal for duplicating a good gem (more often than not anyway), this will save you the effort of duplicating and merging; as we said, this is a convenience and thus the mana cost will be the same as if you duplicated and used the combine function.
