Do Baal give no extra reward (drop or XP) when terrorized?

From what I understand Monster that normally have higher level than the max level for the TZ (TZ level for normals; TZ level + 2 for champions; and TZ +3 for uniques) keeps his original level and will be exactly the same as his non-terrorized version.
If this is true, Baal, that has L99, will never be terrorized (max TZ level is 96...)
And the same will be true for Diablo (L94) if TZ level is 91-
and Nihlathak (L95) if TZ level is 92-

So, if TZ time is running out, maybe it is better - for XP - to kill more "regular monsters" and let Baal to be killed after TZ runs out, then rush to kill Baal (or Diablo/ Nihlathak depending on the TZ level...)

Not 100% sure about exp, but the monster level logic is correct.

This has some funny item drop consequences:

Baal has the lower TC87 loot table (0,1% weap87, 0,1% armo87) and he only gets higher TC87 loot table (1,0% weap87, 0,5% armo87) on Terror level 96, when his native mlvl 99 gets replaced with TZ'd mlvl 99.

All the other bosses get the higher TC87 loot table on Terror level 93.

TZ'd Andariel gets same loot as Baal when you're lvl 88-90, with signicicantly better chances for TC87 items than Baal when you're lvl 91-93.

Don't do Baal if you hunt for TC87 items unless you're lvl 94+.
