I play so few with them that i forgot how squishy the Yeeks can be
I played a Yeek Summoner that was becoming very good, powerfull summons and leveled quickly so he was up to level 20 when i reached Maze (what a difference from when i play skeleton with them i always struggle to reach level 14 at the time i go to Maze).
I got the alternate layout of Maze this time, with the small floors and the holes to reach lower levels, my first.
All seemed to go well until i reached the last floor.
At some point of the exploration i spotted the boss (a corrupted version of a minotaur with tentacles around him) and sent my Drake squad to deal with him while i retreated behind cover to summon something else.
In the middle of that battle, i decided to move up to summon another Drake squad close to where the boss was fighting, but i got bad luck with my timing as it was just in time for him to destroy a drake and get a direct line of sight on me.
Saving/Loading/Saving ... huh ? Eidolon ... wow, the thing just insta killed my character , and from the log it was with 3 shots of +/-100 damage each and another one of a different damage that i was resistant against, but that went over what the few health that was left after the 3 hits, all on the same turn as i did no other action after moving up.
And it was then i remembered .. Yeek ... Health ... Constitution ... damn i forgot after getting such a good run up to Maze that they have nearly no health.
Once i managed to deal with that boss and put an end to the thing, i explored what was left of the floor, moved around a corned and noticed that headless corpse monster surrounded by floating eyes.
Yeah, in Maze ... you know that headless corpse and floating eyes monster that is really dangerous even by the time you're reaching the East.
Save/Load/Save . .Eidolon again, in the log the eyes all shot my character and due to how insanely squishy he was, another instakill.
I'll remember next time i play a Yeek, Constitution ! put points in Constitution even if the skills require other traits, Constitution is what prevent an insta kill on a Yeek ! Remember that at some point of the campaign, the big monsters will deal more damage by turn than what the Yeek will have for health if no Constitution upgrade !
Unfortunately, poor Yeek ran out of life fighting Urkis that killed him a few times.
As even if i increased constitution for the few levels i gained from Maze-Sandworm-Daikara (that went all rather very well) , i didn't found enough cold+lightning resistance items apparently (i had only between 35 and 40% res unfortunately) to prevent Urik to freeze my character from out of sight and kill him a few turns later before i could break out of the ice, the summons being completely useless during that time as their AI seems to be more busy attacking your ice prison instead of Urkis, while he happily lightning bolted me to death in 3 or 4 turns as none of the damned summon was trying to attack him
And from what i read in log, it looks like when you're in ice , your summon do not only attack your ice prison, as when i summoned a turtle, hoping Urkis would be distracted enough to give me time to break the ice, i saw that my drakes were all attackin my turtle !
