For the first time, I successfully managed to get a Sorcerer to lvl 14.
After some agonizing, I picked Spell Sequencer as my first lvl 7 pick and had an epihany:
** Sequencers function like mini-Time Stops. **
Allow me to explain:
My Dragon Disciple now starts any non-trivial fight with SIX spells within the first 7 seconds, i.e., by the time of the beginning of the second round, I have:
* fire Spell Sequencer -> cast Spell Sequencer -> fire the newly loaded Spell Sequencer
So, within first 7 seconds I typically end up casting (reflecting my current spell picks):
(Blur + Fire Shield + Imp Inv) + (3 x Ice Storm OR 3 x Fireball OR Slow+Glitterdust+Acid Arrow)
I suppose Spell Trigger opens options such as:
(PfMW + True Sight + Spell Imm) + (Malison [picking it later] + Chaos + Slow OR 3 x Chain Lightning)
I know this may be already obvious to the experts, but I just noticed the impact of such triggers on the power curve:
You expand one lvl 7  spell [and another one before you engage; possibly at rest] to cast SIX lvl 4  spells in the opening round of a though fight.
I realized that my Dragon Disciple can in principle destroy any cluster of Vampires:
1. buff with (PfMW + Chaotic Commands) just in case
2. unleash 6 x Fireball before they can even hit you (the last 3 likely need to be targeted on yourself as they will rush you)
(On principle, I'll refuse to pick Project Image [it should exhaust your own spell book; not duplicate it].)
I probably stumbled on something obvious to the experts, but it is very exciting.
What are some awesome combinations people successfully used?
How about Cleric/Mages?
Do you keep Sequencers memorized regularly or just use them as emergency backups?
