Just had a Cho'gath rush Rylai's.
Yes. He's an old champion so even though it appears to be a proc-based effect (which does not apply Rylai), it's treated as an AoE spell for the purpose of applying Rylai's.
free frozen mallet
and gives you the multi-target slow rate, which is less than that of mallet by a fair margin
not that rylai's is bad on him just saying these things need to be considered
Since for the purpose of Rylais, yes, vorpal spikes ARE a spell, they deal magic damage so they apply Rylais slow, though in the AOE version of it since the spikes don't give a **** on who they hit.
Unless they fixed it, Vorpal Spikes procs on-hit effects. Why not just build a Mallet if you want a decent slow?
