When shooting at Zephyr's tornados with incarnon mode weapons, incarnon modes don't crit. I've only tested it with the ones available to me, which are latron, paris, felarx, laetum, and ceramic dagger. It only seems to occur with non-melee weapons, but I only tried it with ceramic dagger projectiles. Direct hits on enemies can crit, but shots that only hit the tornados don't crit. Normal weapon modes can crit. Tested in missions both in solo and co-op. Not just a visual bug, as time to kill noticeably dropped.
