Standard Cross Converter.
Overall
B
(A at BT2)
(SS at MBT)
Advantages
+At max BT: Preemptive conversion is vital
+Cross conversion generates a lot of tiles, at minimum
Disadvantages
-Awful CD without BT2
-The actual pattern of cross conversion is awkward for high-damage set-ups without other forms of conversion or some RNG
Explanation
Cross converters are radically different based on if you have obtained Max Breakthroughs (MBTs) or not. When not fully maxed, they're clunky (if serviceable) options for large amounts of tile generation, similar to Raphael or Uriel. The BT0 cooldown effectively prevents you from getting to use them more than once on a normal 10-turn level, so even BT2 can be a pretty significant upgrade.
However, once you MBT them, they are arguably the best units in the game and have a staple slot on basically any team that demands high tile count. While the four-tile converters should carry you through 99% of the game, obtaining MBT Cross Converters should be a long term goal, as they tend to simplify most content.
Even among other Cross Converters, Barton stands out, thanks to his extremely powerful equipment giving him access to diagonal attacks and a mild damage amp. The result is an all-around must run if you intend to min-max your Water comps.
