Just played a game as rammus with a trundle on the other team and found a bug. Not sure if this has been posted already, but when trundle ults rammus while he has spike shell activated, rammus armor gets absolutely destroyed. I went from 900 armor to -160 armor during a teamfight.

Trundle ults me, my armor quickly decays to -160 armor: https://i.imgur.com/Yp2RKYj.png

The armor reduction lingers for about 8 seconds: https://i.imgur.com/NvOXkZD.png

This happened twice in the same game.

That isn't a bug.

Trundle's ultimate determines the amount of stats it will steal at the time of casting. Even if your armor happens to be reduced in that duration (i.e. Defensive Ball Curl deactivates), the amount Trundle will steal remains unchanged.

If you had 900 armor when Trundle used his ultimate, Subjugation will steal 360 armor from you over it's duration.

Subjugation has the same interaction with Sejuani's passive.

That is not a bug. Trundle steals 40% of your current MR and armor at cast. Spike shell is giving Rammus more armor, so Trundle presses R and steals 40% of that huge amount(40% of 900 is 360). Half of that 360 reduction is applied instantly, the other half 4 seconds later. When spike shell goes away Rammus losses that bonus armor but Trundle is still removing that huge amount (360)- enough to push Rammus's armor into the negative when it reverts back to the lower amount (apparently around 200) when spike shell is off. It lasts 8 seconds because that is how long Trundle's R lasts.

Which is why you need to be careful against Trundles if you are a champ that gets a huge bonus to your armor and/or MR (e.g., sej, rammus, malphite, etc).
