I dunno if this has been pointed out yet, but the duration of Twin Snakes could really increase slightly.
It almost seems like they didn't expect us to do two True Strikes, like it wasn't intended.
So we're just losing that 10% extra damage on Twin Snakes if we do two True Strikes and it's insanely tight timing if you just divert you attention or have to move away for even a second then nope.
