Been a while since I've reviewed the playtest, so this may have been covered elsewhere, but I'm confused as to the use cases where Memory Strike is in any way better than Warrior's Incantation. For sake of ease, here's the playtest text for both:
Memory Strike (Item [Weapon]) - Memory Strike allows a weapon to be charged, once per day, with a spell from memory of the same Aspect as the Ritual. This will expire at the next logistics. In order to do this the Caster will need touch cast the spell to be charged onto the weapon in a Circle of Power of the Aspect of the spell to be charged. This can also be done at logistics even if you do not have access to a Circle of Power. When the spell is channeled through the weapon as a spellstrike, the wielder does not need to fully incant the spell or use magical aura. The Qualifier for spellstrike delivered spells is 'Spell'.
Warrior's Incantation (Item [Weapon]) - This Ritual allows the wielder of the weapon the Ritual is cast upon to use a Ritual charge and a spell of the item's Aspect from memory to spellstrike that spell (once per charge) through their weapon. When the spell is channeled through the weapon as a spellstrike, the wielder does not need to fully incant the spell or use magical aura. The qualifier for spellstrike delivered spells is 'Spell'.
Also, WI talks about Ritual Charges, so perhaps it was missed in the most recent changes?
