A mimetic plant monster that appears out of nowhere and uses Cryo in combat. These plants lurk under the surface and ambush unsuspecting prey. With the passage of years, sufficient nutrition, and the right environment, it could even take root somewhere and grow into a giant Cryo Regisvine...
The following table describes the level scaling. Note that values may change in Co-Op, some Quests, and certain Domains (such as the Spiral Abyss). The change usually involves multiplying some of the values by a constant scale factor.
Burrow: The Whopperflower sinks into the ground and emerges nearby.
Melee AoE: With a player in melee range of the Whopperflower, it may do a short animation spinning its leaves and doing an AoE capable of hitting a maximum of three times.
Ranged Attack: If a player is not in melee range, the Whopperflower will instead shoot out spikes from the ground that goes to the target.
Charged Attack: The Whopperflower will close its leaves, consuming one of the "crystals" orbiting around it. When a "crystal" is finished, it will create a Cryo shield, giving it ~10 seconds to charge up its attack. If allowed to fully charge, it will bend over, point its top at the player, start spinning like a Gatling cannon and shoot out a rapid volley of Cryo projectiles; however, the shield can be broken to prevent its attack and stun it for ~15 seconds.
Recharge: Once all three "crystals" are consumed, the Whopperflower will plunge into the ground and restore all three, creating a visual AoE but will not do any DMG.
