Inspired by the Battle-Pods in deconstruction zones.

Edited for further clarity.

Appearance:

• About the size, or the size of 2 side-by-side alpha wolvers
• Albino color-pattern like this
• Chromalisk model depending on tier
• Dragon Wings in T3

Fight:

• Invulnerable while invisible
• While invisible, moves around and spits multiple hazard-tiles at once (T1=3, T2=4, T3=5)
• Each individual hazard-tile's effect is chosen randomly
• The status effect inflicted gets stronger the higher the tier, stopping either at moderate or strong at T3
• Curse is not encountered in T1, has below average chance to be generated at T2 and is generated as often as the other effects at T3
• The tongue attack reaches 5 tiles across and drags knights towards the 'lisk when hit
• Blocking the tongue causes moderate knockback
• Blocking the sides of the tongue also causes knockback

Further Attributes:

• 3/4 the health of a Battlepod.
• The vulnerability-phase is as long as a Battle Pod's, but the invulnerability-phase's duration is halved
• Invulnerability-phase is focused on laying out hazards
• Vulnerability-phase is focused on dragging knights into them
• Spawns with 3, 4 and 5 healers depending on the tier and attempts to spawn 1, 2 and 3 additional healers each time it switches phases, to a maximum of 4, 6 and 8 healers respectively
• Healers are most likely Silkwings, but rather this.

Concept:

• Knights are exposed to be dragged through multiple hazard-tiles and be inflicted various status-effects at once
• The fight has two phases with the intention to give the 'lisk time to build up a dangerous terrain
• The removal of the healers is key to victory and gives the knight a reason to navigate said terrain and making it less a waiting game
• The pull-and-push mechanic of the tongue opens up new strategies, e.g: when to block or bite the bullet to avoid hazard tiles, or when to use the pull to bridge the distance for an attack

Note:
While revising, I noticed that either the duration of the hazard-tiles has to be expanded, or the switches between phases has to be shortened. I'll leave that up to feedback, guys!

Optional:

• Could steal pickups like a Kleptolisk
• Could either rotate periodically between damage-type resistances while changing to the respective color or make it dependent on the amount of damage dealt with a weapon of the respective damage-type, as suggested by Defeat
• As suggested by Jessecho, there could be support-'lisks spawning at different points during the battle, but I feel it could be overkill by now
• Nonetheless there are some unused Chroma-eggs that could fit in some way or another
• At T3 it could drop prismatic dragon-wings with a low chance

The Basilisk:
More a joke suggestion at first but it could actually work?
I has the same model as the Prismalisk but chicken-wings at T3 instead and Chroma textures all the way through.
The fight is also the same but it only spits stun-hazard-tiles.
Also Basil could be riding it... or it could simply drop Basil-only receipts with a low chance.

The stun and curse hazard-tiles should be rather easy to implement i think, but the A.I., the tongue mechanics and the, for that very reason, optional damage-type-resistance rotation are probably more code-heavy.

Post your ideas, suggestions and criticism :)
Thank you for the feedback so far!
