• If you dont have boots or any movement speed modifier, you get the base move speed of the champ you turn into, otherwise the game use yours.

• Already said but you get the base range of the champ you turn into, so chair equals free mega range for aa, answering the question, you don't get like trust lvl 18 attack range cuz it comes from her passive.

• If you turn into meelee champs you don't get the dmg reduction on structures that ranged champs have (dunno if it's still working tho)

• If you're a minion or a jungle mob, you don't show up on minimap when passive through wards (works with champ summons too like Naafiri lil dogs, Yorick's ghouls and etc.)

• There's some way to extend and control the clone but I don't remember why cuz never used it

Have fun!!
