Writing "in your opinion" is meaningless and does not invalidate anything that I wrote, since what you've been writing here is also "your opinion".
I can become more intelligent, stronger and/or faster, but none of those things will make my car run any faster.If the equipped weapon is increasing the Tinker’s intellect and stamina, then that would positively effect how the Tinker operates the mech. It would also allow the Tinker to create more powerful and efficient weaponry.
A fireball cast by a mage is amplified by the magic within the mage's staff because the fireball comes from the mage itself. A rocket fired from a tinker would not come "from the tinker" but from a device outside the tinker's person. As in, not part of the tinker's self.And I gave you a valid explanation for a Tinker using technology to do the exact same thing. Also empowered weapons would empower the Tinker like any other character. The use of technology does not shut off a character from magical effects.
You're missing the point. It is evidence that magic does not necessarily means "magic damage".That’s a nature spell. Auto-attacking isn’t a spell.
