GMST Class Testing

Also, back to actual I/L Tespia related matters:
1. Is Meditate a smart buff i.e. can it stack with pots or more unlikely Bless?
2. What damage increase (%?) does ID's ice weakness apply and more directly, does said weakness affect the damage of Elquines? Useful for further DPM calculations I am doing...
3. How was the Ifrit to Equines transfer accomplished, just a basic conversion?
4. Does Buff Mastery affect Infinity, if so, does the percent multiplier pass +100%, I realize few people have level 30 Infinity.
5. It has already been answered but I cannot remember in which thread or page but I remember DoT and Summons are unaffected by both Amp and E.Weaponry, right?

1. No, it's like Rage and can cancel any non-stacking attack buff.
2. Ice Demon makes monsters take 50% more damage from Ice attacks, including Elquines's attacks.
3. Skills are kept track of by their skill ID, not their name or appearance. Basically, if you had a mastery level of 30 in skill #2121005 (or #2221005), you will still have that mastery level after BB. The only thing that changed was that #2221005 is now Elquines whereas it used to be Ifrit. Mastery books change the mastery level of the skill they are attached to by skill ID, so all they had to do was rename the Ifrit books to Elquines.

5. Amp affects summon damage last time I checked, it does not affect DoT damage. Elemental weapons do not appear to affect either.
