A few bugs with Trials of Chaos and one for Delirium

Trials of Chaos:

1) Reduced Recovery (40% less) doesn't seem to be 40% less. I had 175 mana regen and taking it dropped it to 155. Could it possibly be coded as 40% reduced?

2) Lightning Runes don't stop when the trial is over.

3) My pathfinder's "Unaffected by Slows" does not work on the slow from Heart Tethers. Neither does Wanderlust's mod.

Delirium:

When I do a Delirum map and end with say 4 stacks complete, I get like 5-10 splinters on average. When I use the unique tablet that makes delirium not end, I get 5-10 splinters for EVERY stack that completes. Is Delirium w/o the tablet potentially handing out much fewer splinters than intended?
