Lab time tuesday !
-For some reason, the PMBR decided that Snake was stronger than Ivysaur so his tranquilizer can put to sleep opponent while they're doing something, while our stun seed only stuns people that are either running, crouching, walking or standing. (Our stun seed behaves like jiggs' sing, it's actually Snake's saltylizer which is the exception)
-As you probably know, each dair gives you a slightly lesser boost than the previous one. The only way to refresh this is to land, not touch the ledge. First dair stops your vertical momentum and gives a slight upwards boost. Second dair stops your momentum and seems to hold you in place for a bit. Third dair and all subsequent dairs just stop your vertical momentum. If you hold down during a dair, it doesn't count, you can still get the fully powered dair afterwards.
-After a grounded footstool (which you can do while the opponent is shielding in example), hold down dair hits with the sourspot, and uair hits with the meteor hitbox. Uair allows you to combo better after about 70%, but will not work under platforms on taller characters such as Snake in example.
-There is a small amount of time you are forced to stay on the ledge (about the amount of time it takes for the "bubble" thingy to disappear), but not on tether recoveries. However, the amount of invincibility we get from a ledge catch seems to be shorter to compensate, I can't seem to make my ledge wavedash safer or riskier by grabbing the ledge or by tethering it.
