Gromma Nander is one of the Champions of Idle Champions of the Forgotten Realms. She was obtained from the Feast of the Moon event and again during the 7th year of The Great Modron March event, or through Time Gates or purchased through the in-game shop.

Gromma is a versatile Tank and Support Champion. Her Druid Circle specializations offer different tanking options depending on the situation, while her Grandmotherly Love formation ability buffs your party, with the youngest Champions receiving the greatest benefit.

Once unlocked, you can swap this Event Champion with Nayeli in slot 3.

Backstory[]

Extremely elderly for a Tortle, Gromma Nander grew discontent with her secluded life after giving birth to her offspring. Once they were old enough to fend for themselves, she ventured back out into the world to learn as much as she could about the strange creatures that inhabit it. Gromma is a wise and inquisitive Tortle who is quick to friendship but slow to trust. She carries a pouch of smooth colored stones that she has collected on her journey and walks with the aid of a battle-worn spear.

Abilities[]

Gromma's normal attack can change based on her specialization. She starts with Slow and Steady and changes to Melf's Acid Arrow if the Melf's Acid Arrow specialization is chosen.

Slow and Steady – Base Attack

Gromma Nander, moving faster than you would expect for an 80 year old Tortle, stabs the closest enemy with her spear.

Melf's Acid Arrow - Base Attack

Gromma shoots a bolt of acid at the nearest target.

Hardened Shell – Level 25 Ability

Gromma has a hardened shell, reducing effects of the Overwhelm debuff by 25%.

Grandmotherly Love – Level 90 Ability

Gromma increases the damage of all other heroes proportional to their age. The buff starts applying to each Champion at 100%, and for every 10 years younger than 100 that Champion is, the buff on them is increased by 100%, stacking multiplicatively.

Specialization Choice – Level 100

File:Icon Specialization Gromma Melf's Acid Arrow.png Melf's Acid Arrow - Replaces Gromma's base attack with Melf's Acid Arrow, changing her into a magic attacker. After hitting its target (dealing damage) the arrow explodes, damaging it's target (again) and all nearby enemies for an additional 5 seconds of BUD damage.
