Creatures of Ava

The overcharge skill allow you to double the absorption power for a limited amount of time, 4 seconds considering the cost as 25 mana/second (max 100 mana).

To get the achievement I upgraded the Ushun skill to the third level (when you use the ability you gain +25 overcharge mana, so one more second).

So, the procedure is:

• start using the overcharge skill for a couple of seconds

• keeping overcharge active, cast Ushun to gain one more second

• keep going with overcharge till you reach 5 seconds

Be careful, if some creature hit you the skill is interrupted and you have to start over.

A good place to try is in south part of the Nari Jungle, with Batar creatures.
