Possible Item upgrades (below tier 4, to replace Topaz of Str):
Item 1: Staff of Minor Healing
Item 3: Mask of Stolen Mien
Tier 4 upgrades:
Weapon: Sawtooth Sabre +2 (replace Shock Glaive because it's not finesse)
Armor: Spell Ward Shield (replace Stanching Buckler?)
Item: None
Ally: Psychometrist, (Maybe?) Zealot.
Blessing: None
Skill Feat: +3 Str
Power Feat Daredevil: reduce dmg to another character at my location by 1
Card Feat: Ally (which would bring me to my limit of 5). Or Weapon? The weapon choices are becoming very nice, but since I rarely need to discard my weapons, probably better to take Ally so I can add Psychometrist without losing one of my existing allies (or add the existing one back when I gain this feat if I already swapped it out for Psychometrist).
Tier 5 upgrades:
Weapon: Flaming Ranseur +3 (note it's not Finesse, but still very good), Humanbane Gladius, Vampiric Backsword
Armor: Armor of Skulls (have to check if this is an upgrade from Diviner's Blight or Spell Ward Shield)
Item: Boots of Teleportation
Ally: Heister
Blessing: None
Skill Feat: +4 Str or +2 Cha?
Power Feat Daredevil: reduce dmg to another character at my location by 2
Card Feat: Weapon
Tier 6 upgrades:
Weapon: Corrosive Backsword
Armor: None
Item: Sihedron Ring (check if this stacks with Armor dmg reduction), Ring of Energy Resistance (check if this stacks with Armor dmg reduction)
Ally: Maybe none? Consider: Eyebiter, Isiem, Thrune Agent
Blessing: Blessing of the Eternal Rose? (Might not be better than what I already have)
Skill Feat: +4 Str or +3 Cha
Power Feat Daredevil: Hand Size 6
Card Feat: Weapon
