Finally i did this stage 19.
I built my yannica with a stun set, and she worked as i tought. She is fantastic here, constant aoe attack
that allow me to control spiderlings. She puts a lot of leech too.
Inspiring by this, i had an ingenious idea for stage 20
Stage 20 is green, so red is weak affinity.
Then i builded my sinesha with a retailation set, and with all of those leech on spiderlings, whenever counterattack proc she gets a massive heal. So is basically a counterattack set + lifesteal set in one, using Yannica.
I builded my team with only 1 red champion, Sinesha, to be sure that spiderlings go on her.
The team is: Yannica(L), Apothecary, Stag Knight, Coldhearth, Sinesha.
When the run start, this seems work. Stag Knight puts aoe def break, Yannica puts aoe leech, spiderlings go on sinesha and after 3-4 hits she counterattacks and suddenly her life is full. This has been going on for some time, and when i start to believe in success, the unexpected happens.
At certain point of the run, often after a spider attack, spiderlings go suddenly on Coldhearth, without any reason, and the run fails.
So, the spiderlings AI does not work attacking the weakest affinity? I've been careful using a red champion, to be sure that spiderlings go on him and not on others champions.
Why this happen? It's a really shame, the idea is fantastic and works good until this happens.
Where i'm wrong?
Before someone can answers me that probably Coldhearth has less hp than others, Sinesha has 29k HP and Coldhearth 33k, so this is really without reason.
This Arbiter is making me suffer a lot!
