That & it turns into a massive Karma sink too since you keep wanting to learn more & more spells to "buff" yourself with.
Well the minimum amount of Karma you spend per spell is 1. Anything else just gives a bonus to dispelling, which is nice fo course, but maybe not too often relevant.
So for 1 karma you can get the semi-permanent benefit of Wired Reflexes 3, or increase an attribute by 4 etc... That is EXTREMELY cheap.
Even if it only lasts for a while, and you have to recast it every month or so.
I think you completely missed what I said. Let me emphasize above in bold for you.
Its not 1 Karma. Its 6 Karma, you learn the spell, then you quicken it. It adds up fast.
Unless you took nothing but buff spells at chargen which makes little sense since buff spells, while nifty for making you hard to kill, are not a very diverse & useful set up for a mage.
A "typical" buff gives you 4 dice for some test. Nice, but not the kind of boost that Having or NOT Having Improved Invis, or Levitate, or Fire Ball, or Control Thoughts, or Physical Mask, or Heal, or Detect Enemies XR, or Fashion, or .......... well you get the picture.
Buffs make you better "defensively", but short of some boosted Drain dice, they do very little to improve a mage "Offensively" the way more diverse spell selection & power foci do.
