Mecha-Bruce

Mecha-Bruce is one of the special Rank 6 Challenge Card encounters in the Brawler's Guild. To fight him, players must use Challenge Card: Mecha-Bruce, purchased from the card trader in the arena. To unlock the ability to purchase the challenge card, players must first purchase Challenge Card: Bruce from the same card trader and beat Bruce once again. A quest-starting item will automatically be awarded upon Bruce's second death.

Strategy
Mecha-Bruce cycles between Chomp x7, then Better, Stronger, Faster, and then Stasis Beam. Keep Mecha-Bruce in one corner of the arena until he starts the upgrade and stasis casts, then sprint to the opposite corner of the room so the stun wears off before he closes the gap to chomp chomp chomp again.

Mecha-Bruce's 6.5 million health means he needs nearly 55K DPS to beat the enrage timer.
