- Spell proficiency has been revised to include rules for spell foci. If you have an ability that makes an item a spell focus, you can apply its properties to your spells and use it to deliver spells as melee attacks. These abilities are similar to the old Spell Strike proficiency and Staff Attunement merit, both of which have been dropped.
- Somatic Spell + 1 has been replaced by Spell Focus + 1. This adds one point of damage to your spell attacks so long as you are unarmed or wield a spell focus.
- Staff Spell + 1 has been replaced by Staff Focus. This allows you to treat any straight, blunt weapon as a focus, including staves (heavy weapons), rods (medium weapons), and wands (light weapons).
- The new Unarmed Focus proficiency allows you to treat your unarmed attacks as spell foci. Note that, by extension, this allows you to apply obi properties to your spells.
- The new Spellsword merit allows a dual-classed fighter/mage to treat any weapon as a spell focus.
- The effect of Spellsteel has been changed. Any spellsteel weapon now counts as a spell focus.
- The old effect of Spellsteel is now a part of the Focus Mastery merit. This allows you to use any Spray as a Burst instead.
That is correct. You can also use it to apply hones, or weapon buffs of any kind to your spells as well. The real question is if the new spell foci rules for adding the weapon properties to spells includes the effects of poisons like Iclunia Dust and Bonescour (or whatever it's called)
So if I have a spellsteel sword I can use it as if it were what spell strike used to be?
