Note: Not all units are needed and these are not “Team Builds“. They are recommended units for you to bring to make the fight easier. You may not even need to bring all of the units as the fight may be different for each player due to their box.

Boss	Attribute	Core Hero	Potential Heroes	Information
				Boss Passive: Every Debuff removed recovers 50% of missing HP. 3% increased Crit Chance per skill used. Starts with 2 orbs in the Ultimate Move Gauge. Strategy: Boss can be frozen but recovers HP based off of missing HP & debuffs wearing off. Try to Power Up Lizhawk's ATK with Gilthunder and pummel and rush her Ult.
				Boss Passive: Gains 30% Attack and 50% Crit Chance if Ultimate Move Gauge is completely filled. Immune to Stun, Freeze, and Attack Skill disables. Starts with 2 orbs in the Ultimate Move Gauge. Strategy: High HP boss. It's an easy, but long fight. Reduce Ult Gauge to reduce boss power. Buff with Arthur and aim to get his Ult for main damage. You may also use the Griamore-stall team.
				Boss Passive: Immune to Freeze, Petrify, and Ultimate Move Gauge reduction. Attacks remove 1 enemy card. Strategy: Because the boss does not use Attack Skills, Slater can completely disable her. Use Vivian to disable her Ult, making her completely empty. May not even need a DPS here.

Training Dungeon – Training Grotto

Training Grotto is available after Episode 109.

Unlocking Dungeon requires Training Grotto Key, which takes 5 days to recharge.

Training Dungeon is now finally unlocked!

Here, players will be able to acquire Equipment Engraving Stones, Hammers of Vaizel and other valuable rewards!

Do not that the Equipment Stats do not take into account here, which is similar to Non-Gear PvP Mode or Fight Festival (Normal).

There are 30 Goddess Ambers available after you open the Dungeon. 5 of the Ambers are randomly selected for the battle.

Players can exchange Ambers for free once per day. The next exchanges cost 1 Diamond each.

The heroes used to clear the Goddess Amber can only be used once per event.

Every time you clear the Goddess Ambers, the Illusion Amber gauge above fills up. Once it reached 100%, it will unlock the Illusion Ambers.

The Training Grotto will close after 7 days, or after you defeat all of 9 Goddess Ambers.
