Ok let's talk about potential Caliban augments, here's mine :D

Since we're getting closer to his augments more than ever now...let's talk about ideas and potential new mechanics to explore.

First of all, his passive ability, which is his adaptation and the ability to inflict tau status, I'm going to somehow mix them together, providing benefits from both.

• RAPID ADAPTATION! 
  • Adaptation passive does not Decay, but can only resist 4 damage types at a time.
  • Damage taken from Lethal progeny summons contribute to Caliban's adaptation stacks.
  • Increase max stacks of Tau Status by +2 for each damage type resisted.

this allows Caliban's passive to build resistance more efficiently, one thing to note here is that, it will replace the old resistance when a new one is present.
meaning if Caliban resisted slash, impact, puncture then toxin...and say he got damaged by a new type, the resistances to slash will decay while the new type builds up.

His summons take damage, so like sentients, this damage is now contributed to Caliban's adaptation passive, to allow for much faster adaptation.
allies will get the same too.

for each damage resisted (up to 4) Caliban will be able to deal +2 new tau status...so up to 18 tau procs, which maximizes enemies' vulnerability to status.

Kinda wanna see a Lethal Progeny augment that has Caliban summon one of each of his three sentinels instead of one lot of the three types at a time. Dunno about the other effects it could have (could be a simple buff like +50% strength or ability duration for that ability, or perhaps similar to your idea, the sentinels can also build up adaptation for Caliban's passive) but it'd be neat to be able to use all of his summons at once instead of a specific type at a time?

nice, like Fused reservoir, that would be so cool!
