It is hard to find on the forums as his skills were not officially released and very rarely discussed. Below is the most relevant info we have on his skills:
Iron Patriot is
creates
at your choice of location (up to 6 at max covers!)
places protect tiles at your choice of location, over strike/protect/attack/CD at max rank
is Avengers Assemble for the dark avengers. Avengers assemble summons Rags for starters and he busts columns 2, 3, 6 and 7. 5 AP of the other colors summons the following:
Agreed. Between the purple being placeable crits and the green also have placeable protect tiles, there is a whirlwind of possible winfinity possibilities. However I believe the AP costs for all of his abilities are really high (e.g. Nick Fury). I still think they should release Iron Patriot, they just need to tweak his abilities, like make the crit tiles random.
With multiple critical tiles, are the properties additive or multiplicative? Using Thanos 5* w/ 4x crit multiplier and 671 damage on black as an example. If crits are additive, then we have 6 crits x 4x multiplier = 24x damage, which next to a black tile is 16k damage…but if they’re multiplicative, then we have 4x multiplier ^6crits = 4,096x damage for a cool 2.7m damage, ha ha. Certainly you’d never use the ability that way (Ls, Ts, and Xs would be more useful for cascades), but it’d be hilarious.
The critical tiles aren’t individually placed – they have a set pattern in a star shape and I believe the player selects the center point similar to targeting for 3* Black Widow’s green skill.
Still, that’s a lot of critical tiles at one time.
