Unit Analysis by Team BethelFrankel
Class
Powerful select-tile Converter.
Overall
S
(SS at MBT)
Advantages
+At MBT: Best whale unit in the game
+Flexible, strong tile output with free placement of Prism tiles
+Equipment can provide additional conversion value for next burst (although often unreliable).
+Strong scaling damage on long maps (15-20 turns) because of her marks, especially when paired with Florine and Reinhardt.
Disadvantages
-Prism tiles are an absolute headache to completely optimize
-Slow ramp up on non MBT is a very real drawback on stages with sub-10 time limit
Explanation
Irridon is the best non-preemptive converter in the game and if it weren't for the fact that having preemptive conversion is so much better (and unfortunately hers is locked behind MBT), she would be the best overall converter in the game. It really cannot be overstated just how necessary tile placement is to high impact combos, and the fact that Irridon still maintains a decent tile per turn count (with a powerful Equipment on top!) makes her excellent at even BT0.
Note that in lategame content where preemptive conversion matters less than overall output, Irridon is widely considered an upgrade over the classic 4-tile preemptive converters, and MBT Irridon is the one of the best converters in the game.
