Lord Bot

Lord Bot
"'He's got a grill of gold, a heart of coal, and a desire for power that sends all four arms swinging into battle.'"

Strategy:
The Weaken effect on Pummel is incredibly powerful, so use it early and often, especially on targets that will attack each turn. Uppercut is a powerful and worthwhile attack in most situations, even without the critical damage, but can be punishing when the critical chance hits. If the base damage + critical damage of Uppercut can KO an enemy, unleash it before using other abilities for maximum efficiency. Note that Counter damage is determined by the offense stat, so Counter damage will be higher with an offense buff like Enrage, or reduced if Lord Bot is Weakened.

Items:
For synergy with the Counter trait, use Enrage items to beef up his offense and beat up on enemies when they focus on him. Similarly, you can stack Offense Boost items for a powerful Counter and even harder-hitting Uppercuts. Try adding a Poison item for devastating multi-round damage to any target Lord Bot attacks.

Team:
Lord Bot is all about damaging his enemies, so teaming him with some support characters makes sense. Use a character with Guardian to absorb some damage: a Dwarf will provide another attack with Weaken, while a Knight Errant can provoke enemies away from Lord Bot. A Sorcerer with his bursting Lightning Strike offers some big damage possibilities, while his Quick Heal can provide just enough health to keep everyone upright until the victory is won.
