This is part of a series aimed at people who want to have a quick reference of viable builds for most situations.
It gives general recommendations on when to choose which build, without going deeper into gameplay strategies.

The first build includes general threat levels and short tips for heroes you might want to watch out for.

Bubble Build: The more enemy melees and/or sustained damage, the better. This is a tank/damage hybrid build, weaving in and out of the fight while regenerating with Bubble, mainly dealing damage through slime.

Pufferfish Build: A lot more damage, a lot less survivability. Choose this build if bursting a key target is your highest priority. Rewind is interchangeable with "... And A Shark Too!".
