Hello to all. I have started playing again and wrote up a new Wizard. Its been a few years and the enhancements have changed since then, so could a veteran or experienced dabbler share their wisdom with me.

1. Wizard Wand Heightening I, II, III, etc.

Does the Wand DC calculation include the caster's stat modifier?

For example, Wand of Burning Hands (Level 1 spell, Caster Level 1) be calculated as 10 + spell level (1) + caster level (1) + Wizard stat mod (+3 arbitrator #) + enhancement +1 DC for a DC sum of 16.

Or, would it be calculated without the Wizard stat mod for a sum of DC 13?

I am trying to figure out the DC calculation to weigh in whether using dmg. wands or effects verse using SPs on the spell and to diversify the Wizard to contribute into the fights without draining too many SPs needlessly.

2. Wizard Wand Damage I, II, III, etc.

Simple question here. Do +10% spell effect items effect the casting effect of wands. Such as the Lores, Potency, etc. that increase the dmg. or effect of X lvl and below spells or type of spells.

These two start me off on the line of questions. If someone is willing to shed some light here would be great. I thought they were some cool enhancments but hesitant their ineffective over other choices. Like why take the dmg. amplifiers and controls if other players primarily want the Wizard to play buff bot and only with certain circumstances deal damage a potion couldnt buff. Naturally to my line-of-thinking, brings me to wands as an alt. to be a dmg. class also under the pre-defined expectations and avoid other party members grumbling at the Wizard for wasting their SPs away.
