Mantis Zealot has access to some interesting Blessings, but I think Trickery Blessing is a little redundant.
The Swift Greater Invis is nice here to pick up Concealment (flat-footed is usually good too, but most of Joran's AC is coming from his Armor and Shield), but the Red Shroud ability on Mantis already does that. Likewise the single Mirror Image of the Double ability isn't a great fit in melee where characters naturally get attacked a lot. Image is better on toons that are usually out of the action. The Fading ability already provides a scaling miss chance when Shroud is up. The second Death Blessing level-drain is probably nuts with all the attax it gets and ways to boost its own AB. Think I'll test that.
Notice how much damage Mantis is doing despite not having DEX-to-damage. Minutes of Red Shroud goes by DEX bonus so priced into DEX-based I think.
(1) You can see weapon dice starting to grow. Once Righteous Might/Legendary shows up that will matter more. Sabers have 17-20 with Improved crit so comes up a good bit. Lead Blades not trivial to get but could roll an Oread I guess. I think there is one wand in game.
(2) Not sure what Base Value is.
(3) STR is 14 base + Bull's
(4) Divine Favor tops out at +3/+3 but Divine Power goes up to +6/+6
(5) Enhancement is +1 on the weapon +2 from Sacred Weapon enchanting the class gets. Eventually gets Brilliant Energy. Could use Magic Weapon, Greater here to get another +1.
(6) Good Hope was Encouraging Rod boost from TTT I think. Hope gives damage bonus, Heroism doesn't.
(7) Bracers are +2 AB/AC/Dam Competence vs Flying (Gargs, Vrocks, Derakni, Devarra) for 16k from main vendor. Worth investing in.
(8) Class gets Weapon Spec and later Greater Weapon Spec as essentially forced Bonus Combat Feats. Also gets Greater Weapon Focus that makes Mythic Focus worthwhile. All Warpriests can choose these since it counts as Fighter for Feats.
(9) Inspired Rage is Skald. Unlike Inspire Courage from Bard it's untyped. Downside is melee only.
(10) Mythic Light Armor Focus only works on Light weapons (and Rapiers). Perfect fit for Dual Sabers.
(11) Force is Crusader's Edge that Warpriest can cast on itself.
Inciter Sneaks kick in at lvl 12.
