BOSS - Venomtooth Tiger
Stats / Weaknesses:
- Weak to: Spears, Bows, Fire, Light
Phases:
- The boss conjures a poison pool, making all its attacks inflict poison. It gains two extra shields upon recovering from a break, maxing out at 10 shields after doing this twice.
- At 50% HP, the boss uses Peerless Poison, causing a hazy effect. Characters under poison lose SP and BP.
Strategy:
- The Venomtooth Tiger can perform two actions per turn and inflicts poison with most attacks, including the party-wide Sweep.
- Use skills like Thief’s Shackle Foe to reduce its physical attack.
- Increase party physical defense with Mercenaries from Hired Help.
- Alfyn's Concoct is useful for curing poison. Otherwise, use Herbs of Healing or the Merchant's Rest.
- Focus on breaking the boss before it can perform multiple actions.
- Prioritize curing poison to prevent SP and BP loss, especially after 50% HP.
- After defeating the boss, Tressa obtains the treasure. Return to the tavern for a scene to end the chapter.
