some slight tweaks to magma slide perchance,
 
as it stands, the spell is more or less an objective downgrade to its wave-type basic spell counterparts,

magma slide, 9sd, 25 second cd
blazing wave, 10sd, 20 second cd
mudslide, 8sd, 20 second cd
rolling vines, 10sd, 25 second cd
spatial misdirection, 8sd, 25 second cd
 
noticeable magma slide sits behind the rest of the basic wave-types in both sd, with the two exceptions to this either having a higher base sd to compensate, or a considerably higher tick damage/confuse status like spatial misdirection. also noting, that the tick dmg on magma slide is much lower than blazing wave, and massively lower than what spatial misdirection deals.
 
its closest comparison is probably blazing wave in the tick dmg it deals after, with an added mud effect like that of the earth tree. however unlike these two spells which make up for their relatively low punch and moderate utility, magma slide has an awkwardly high cd. especially when you put it up alongside other skill-shot oriented openers, which all have cooldowns below 20 seconds in exchange for generally being more difficult to land.
 
though as it stands magma slide really doesn't come up often enough to be worth the unique mud effect inside the magma tree, as it lacks the punch or severe status effect to be worth the cd inflicted on it for use.
 
so i think there are two reasonable solutions to make magma slide more appealing and useable as an opener spell,
 
either,
a) raise the sd to 10 in line with say rolling vines, which is another status effect applicating basic wave spell
or b) lower the cd to 20 seconds like its fellow low dmg utility basic wave, the mudslide
