Does Tryndamere's W deal damage if it slows?

Veigar Stun Wal still shows up as 1 True damage in Death Recap a lot.

There's a lot of things in this game that deal 1 true damage

Anivia Wall and Trundle Pillar used to idk if they still do

Its so that you get the assist on the kill but wat about soraka heal

When I press ult I get free assists from all over
