If you get there with specialisations then you have a point; but if you are using foci then you could be disarmed just like the guy with an enchanted item. Except, if your rote depends on that focus then use can't cast the rote.
Sure, sure. But I'm talking
two entirely separate advantages over Items that every Rote has at least
one of (assuming equal degrees of specialization):
1. Better attack numbers.
2. Can't be disarmed.
Rotes relying on Foci have more of the first, but lack the second entirely. See what I'm saying?
Here, here's a graphic example of both versions:
Looking at it, the best you can get with items as a starting character with one slot is a Weapon: 7 attack at a Skill of 5. I can get a higher Weapon rating with enough item slots thrown in (up to Weapon 10 at most), but the skill never goes up. With, admittedly, a larger investment, I can get the same Weapon: 7 attack at skill 10 as an Evocation with a Focus. Without a Focus, I'm reduced to Weapon: 6 at skill 7. Now, those are specialist numbers...but so's the Weapon 7-10 item.
