Ah, a demonstration of how not to construct a character.
Far too few magic items. Unless she's down on her luck. At the least she should have shedloads of scrolls and potions.
Her feats also bite. Still Spell is next to useless at her level of spellcasting, unless you give her Automatic Still Spell (yes, I know it's an Epic feat, but she's near Epic). Why not give her Weapon Mastery instead?
Her full Dex bonus isn't usable in that armour. Mithril Elven Chain +5 might be more appropriate (10 pts Armour Bonus, 6 pts from Dex). Further, in heavy armour, her rogue abilities don't function. Ligh armour would also mean she has a decent chance of casting spells in armour.
Why has she got Tower Shield proficiency if she's using a 2H sword?
No backup weapons.
At L18, I'd expect an Inherent Bonus or two.
Is the BAB right? Shouldn't it be 15/10/5 rather than 15/10/5/0?
I could go on.
