not much of a speedrun, but extremely difficult

it's very simple: pick morph

• buy wraith + tangoes
• level 1: level morph and full STR morph and keep it on indefinitely
• dont level anything again
• go midlane and lasthit
• (lasthits + denies) in 10 minutes are the score
• timer ends when 20th creepwaves(one that spawns 9:30) ingame are killed

you'll constantly have 25~ damage, which is just a bit more than a creep meaning you can technically hit every last hit.

only downside is it's capped at 164 CS(82LH+ 82DN)

for which you'd need to be a god to take all XD
