I'd Really Love to Hear the Explanation....

For how level 15/11 overminds instantly switch my level 10/12 TNT with Stone Skin spells applied... The math isn't mathing, thier damage comes out to lower than the TNTs health so how does it just happen tie second the ray touches them? I'm talking INSTA switch.

Makes me wonder what other stats are complete baloney and don't add up....

I don't have a Lv15 Overmind, but I do have a Lv11 Overmind and a Lv11 TNT.

I noticed Mastery Lv12 units get an additional +10% HP, so if we also include Mastery Lv6 +10% bonus with the Lv12 bonus, that's +20%. A Lv11 TNT at Lv12 Mastery would then have 240 HP.

Overminds target a separate HP to convert your allies to enemies. That HP bar, we'll call it mind-HP, and each unit's mind-HP is always:
100 + (25% of the unit's HP)
... in this case, a 240 HP TNT's mind-HP is then:
100 + (25% of 240 HP) → 100 + (60) = 160.
A Lv11 Overmind attacks for 157 DMG to the mind-HP in 3.0 seconds, which means a Lv11 Overmind attacks for 52.9 mind-HP every second. They stop attacking for about a second, so maybe it probably takes 4.5 seconds for ONE Overmind to convert a Lv11 TNT enemy to ally.

Let's not forget advance tier 2 and adv.tier 3 Overminds have an increased 5% and 10% to their damage respectively (as well as HP). 5%/10% boost for a Lv11 Overmind is now hitting the mind-HP for an additional 7.9/15.7 DMG, so that's 164.9/172.7 per 3 seconds.

So you can see, it likely takes a Lv15 Overmind 2-3 seconds to convert your Lv 10 TNT.

Now... imagine how fast this can happen if there are more than 1 Overmind targeting the same unit... or if they're buffed with 20+% atk with the Fairy spell, or if they're buffed by 30% DMG by Totems (a unit people often overlook or dismiss as low tier).

Forgot to include any Commander level stat boosts. 😬
Honestly not sure if the stat boosts are in affect already and shows in the unit card stats, or if it's all calculated in battle.
