Tactic
Masta Wrangla Glix spawns an add group of trolls for every 20% of health he has lost.
The add group gets stronger each time, with the last wave being a group of level 40 champions trolls.
When the last wave hits, the whole group will receive a stun. Defensive morals should therefore be saved for that moment.
