As Alice stated, all things that require "Rest" can be done simultaneously. Wizard packets are Rest - I know, because you can rest to reset Wizard packets, Bound packets, and Primary Shield simultaneously. Compare this to the new skills in Battlemage, which explicitly state that they are Activity, not Rest, and therefore can only be reset one at a time.
As to whether or not the bolts stack, should you purchase a metric fuck-ton of Air, let's go to the skill description:
"While the grandiose explosions are nice, wizards sometimes opt to slowly pound their targets to jelly. It’s more disconcerting. You may spend AAA while meditating for 2 minutes to call “Imbue to Self by X.” You may then throw 5 packets for “1 Damage by X.” You may reset these packets by meditating for 2 minutes any number of times. This ability expires when you Reset. When taking this skill choose one of the following to be X: Fire, Wind, Stone, Ice, Sound, Lightning, or Acid."
There is no clause in this skill description that states that you cannot have more than one copy of this Imbue. Think of it this way - when you cast the spell, you get a buff with the following text:
"You may throw 5 packets for “1 Damage by X.” You may reset these packets by meditating for 2 minutes any number of times. This ability expires when you Reset."
If I get a second copy of that buff, it just means I have five more packets to throw before I need to take a knee for two minutes and get them back.
As a side note: the Grant rules are a little more complex than just "max 3 Grants". You can have one Grant Protection, one Grant Armor, one Grant Vitality, one Grant of each stat (air earth fire water void), and three Granted attacks and/or defenses.Statistics: Posted by Ariel — Wed Nov 04, 2015 10:05 pm
