>>35341139As ice elementals, ice-type Pokemon probably only possess the ability to produce ice due to the origin of their element. Assuming the element is produced from, say, some kind of gland as opposed to, say, oblivion, then said gland is probably rigged in such a way that doesn't allow for the production of water, even when burned. OP would make for a good move gimmick or a bit of lore for a future Pokemon, though.
