Tetra is one of the best support in summoner’s war. She got a huge HP and defence pool. And also she is very very fast.

Her first skill Mana Bubble basically attacks an enemy that has 50% chance to remove beneficial effect. Most notably this skill is scaled through his max HP. So this compliment her high base HP. Pretty awesome.

The second skill removes all harmful effects on ally target and cast a shield for 3 turns. It is not as effective as the aoe shield of sylphid, but this is still awesome because of the harmful effect removal.

The first skill and the second skill is already good but her third skill makes her amazing. She attacks all enemies and put them all into sleep for 1 turn. That is very very deadly to the enemy. This skill cannot be resisted not unless the monsters has sleep immunity (for example Dark Salamander).

I would recommend to rune her Swift/Energy. And on slot 2 put speed, slot 4 and 6 should be HP %. If you rune her like this, you got a speedy tank support. All in one.

So where you can use Tetra?

You can use Tetra  with almost everywhere. Tetra is useful in toa, arena, giant, dragon, etc.

Final Verdict:

Very good support monster
