Path of Radiance
Honestly, I keep bailing on Titania for Kieran in this game. Her stats are subpar. On average, you’re looking at a -5 Str and a -5 Def deficit if you choose Titania over Kieran. That’s because Titania is this game’s Jeigan.
Giving her the Knight Ward makes her fast, just like the rest of the Paladins, but her Str needs an item-related buff. She looks like she’d be best suited to taking on pegasi, and I guess mages (her Res is +3 on Kieran on average).
I will make an attempt on her eventually, but right now I see her as a temporary unit who covers your flanks and chips enemies in the earlygame to help bolster the battle abilities of your other units.
Okay, last time she was a Jeigan, and this time she’s an Oifaye. She caps Str immediately as a Paladin, already dropping her total growths under 300%, so she needs Blossom or BEXP ASAP. Her Def growth is still weak, but this time she builds Str, Skl, and Spd quickly, so she’s kind of like a mounted Myrmidon who switched to axes, if that makes sense. Or a mounted Hero. Whichever one of those floats your boat.
If used, Titania will be the first Merc to third tier, no doubt about it. Because of that, if she’s not held back to Blossom/BEXP train, she will be an exp vacuum and inhibit other Mercs’ growth. You’re looking to cap Str, Skl, and maybe Def before promotion, to give her the drop on reaching her third tier caps.
When she hits third tier, the caps move, and she starts over, but she still wants to be using Blossom to pace her levels. She’s very capable of being level 8 Gold Knight before P4, but we don’t want that; it leaves her too little room for leveling through P4 and the tower, so Blossom, please.
With Blossom, her Str will cap at around level 6 Gold Knight, her Skl will follow, then Spd. When she caps those three, pull her out of frequent battle and try to push her exp to just under leveling up for a while, to get some solid BEXP levels. You’re looking to push that Def to capping, so that the other stats can follow.
In RD, Titania is a possible candidate for all-capping, she just takes a lot of care. She’s not a personal favorite, but she’s very viable this time around. In fact, if you want a Gold Knight, she’s pretty much the candidate.
