Taunt= PI?

[AtomicKitKat]

You need Taunt level 49 to get the -101% effect anyway. At slvl 50, the stats for both skills are:

Taunt:
Target's Damage: -103%
Target's Attack: -103%

BattleCry:
Target's Damage: -74%
Target's Defense: -148%

Note that at this point, BattleCry has caused the target to be essentially ITD(and possibly even ITD to characters of much lower clvl than the target)

To ACHIEVE slvl 50:

+1 from Battle Command
+2 SoJ(+1 per SoJ)
+2 Arkaine's Valor
+3 Warcries Helmet
+3 Skill-specific Helmet(on the same helmet of course!)
+3 Amulet
+6 (2*Echoing swords with +3 to warcries each)
+10 (Sounding Grand Charms)
Total:
+30 to X skill, +27 to all warcries.

And 20 in the specific skill of course! The advantages of using Battle Cry over Taunt are of course, that your opponent becomes ITD at some point, and it affects players(and bosses!) as well as monsters. I think. I'll have to test this out later. Seriously though, Slvl 50 WarCry? O_o 59 mana per shot, 390-400 damage per hit, and 10.8 seconds stun! OUCH! For both sides!
