Decided to mess around with Toal's EX version a bit today, and found out some interesting things. First, his Wind skill can actually damage the enemies in the Flooded Prison that only the Thunder skill is supposed to be capable of. It did seem random whether or not it'd actually do damage, but I was able to eventually kill them (grabbing the oxygen fruits as needed). This skip may seem worthless at first, but as it turns out, his Wind skill can also break down the cracked walls. So, it's just a matter of how long it takes (it took me a while, but then again, I didn't bother getting the Cleria Ores at that point). Stranger still, his Wind skill is able to light torches (jump and use it), in addition to the Thunder skill (making him the only character to have all 3 skills able to do this XD). So, all he really needs is the Wind skill to get through the game (as mentioned earlier, his Wind/Fire skills can penetrate Dalles' barriers, and the Fire skill can also be skipped). Oh yeah, I forgot to mention that he can use the Wind skill to bypass the barrier leading to the Dash ability, much like Yunica can WW through, but it does seem kinda precise (plus I'm sure his normal version would be able to do this as well).
Anyway, I tried this stuff in the Steam version, and only for Toal EX; I haven't tried normal Toal yet, and I haven't tried this in 1.1.1.0 yet (and I doubt I will for a while). I did briefly test whether Yunica EX's WW could light torches, but it doesn't seem possible; I doubt it's able to do any of the other glitched stuff Toal's can, but who knows (I guess we should check Hugo EX as well)?
EDIT: Nope, Hugo EX (and probably normal Hugo by extension) seems to be perfectly normal... figures. For anyone who doesn't know, it would seem that the first switch skip I showed is not possible without Dash, or if it is possible, it's TAS only - meaning he has very little of note glitch/skip-wise. About the only things I can think of are using the glitched diagonal wall jumps to bypass activating the tractor beams in the Demonic Core, and skipping one of the switches in the final area (unfortunately, he cannot use it to bypass the first Silent Sands key door, as he cannot maintain enough height to reach that entrance without Double Jump like Yunica and Toal can).
