sometimes it's most effective to only send 1 prepared partymember to combat, e.g. you could prepare Korgan, cast protection spells on him protection from fire/acid/cold/shock, chaotic commands, give him an item with leveldrain immunity when facing vampires (e.g. mace of disruption), then cast Improved haste on him for double movement and double attacks per round and watch the chopping, have him rage when facing mages because he is immune to many effects while raging.
Acquire and use the resources the game offers, buy all green protection scrolls from temples, use potions commulatively, 2 potions of fire resistance = 100% fire resistance, potions of spell resistance, for difficult encounters use potions of mindfocusing (bring DEX up to 25 for better AC, also increases INT useful for fighting mindflayers).
As a Kensai mage there are a few spells which are your bread and butter:
- Spirit Armor: get AC 0 (like Full Plate +1)
- Stoneskin
- Mirror Image
- Blur (-3 AC, commulative)
- IMPROVED HASTE
my most used spells:
- MM
- Chromatic Orb (gets a death effect at lvl12 )
- Spook (has an increasing save penalty)
- Blur
- Mirror Image
- Acid Arrow (can interrupt casting for a few rounds)
- Sculltrap (not capped at 10d6 gets better and better)
- Flamearow (not capped at 10d6 gets better and better)
- MMM (they strike as +5, can be used by mages with cast and attack, cast a spell then spent the rest of the round with attacking something with minute meteors, mages get 5 attacks per round with those)
- Remove magic (better than Dispel, use several copies in sequencers to increase chances that it hits at low levels)
- Pro Fire/Cold, long duration protection spells
- Emotion (underrated spell, can have tremendous effect, use in tandem with malison)
- Farsight (useful at higher levels while using Projected Images & Timestop, because if you move the image to far away from the caster it *disappaers* in the FOW you can't control it, Farsight solves that)
- Fireshield Red/Blue (contrary to description attackers get damaged when they hit you, not only when they damage you, so if their attacks get absorbed by stoneskins they still suffer the retaliation)
- Greater Malison (very important spell, use as combat opener, serves as preparation for many other spells that allow a save)
- Improved Invisibility (you can't be targeted with spells under this effect)
- Minor Sequencer (offensive: 2x MM, 2x Acid Arrow, 2x Chr Orb, defensive: Blur & Mirror Image, or as Cleric/Mage like Aerie : Doom & Chromatic Orb a one shot killer with a save penalty attached)
- Spirit Armor
- Stoneskin
- Teleport Field (can have uses, it's annoying enough if used at you)
- Animate Dead (gets good as soon as you get Skeleton Warriors, but also the normal skeletons are good enough at low lvl since you get a couple of them at once)
- Breach is necessary
- Cloudkill, don't memorize use wands
- Feeblemind (hit a caster with it)
- Lower Resistance (some creatures are spell resistant)
- Pro Acid/Electricity
- Spell Immunity (become Immune to a whole school of magic, e.g. Abjuration, dispel or Imprisonment, or Divination, true sight)
- Spell Shield (block the first breaching attempt like Breach, spell strike etc)
- Sunfire (good damage, ignores spell resistance = drow killer, use in triggers: 3x sunfire)
- Contingiency (cast a spell up to lvl6 without interruption, doesn't count towards 1 spell per round rule)
- Death Fog
- Death Spell (kill weak critters, dismiss summons)
- Improved Haste
- Mislead (stay improved invisible as long as the mislead image exists, park it in safety)
- Pierce Magic
- Pro Magical Energy, long term protection from energy damage spells like MM, Skulltrap, Abi Dhalzims)
- Protection from Magical Weapons (become immune to all weapons that are at least +1)
- Summon Nishruu (see a lich? summon a nishruu for it to play with)
- True Sight (only if you don't have a cleric or inquisitor with true seeing)
- Project Image( copy your caster plus his spellbook to go nova in an encounter for the mere cost of 1 lvl7 spell)
- Spell Sequencer (the possibilities are legion, offensive or defensive, 1xMalison + 2x Remove Magic, 3x Skulltrap, 3x Flamearrow at lvl 20 that'd be 60d6, Malison+Remove Magic+ Emotion, Stoneskin+Imp Invis+ Spirit Armor etc etc)
- Ruby Ray (basically Ruby Ray, Breach and Remove Magic are the only dispelling spells you really need, using others doesn't harm, but those 3 are basic, Ruby Ray to remove spellprotections like spellshield or spell trap, breach to remove combat protection like Stoneskin or ProMW and remove magic to dispell everything else, note that remove magic will work even with liches although they are otherwise immune to spell below lvl6, however they are highlevel so your chances to hit with the dispell are not very good early on -> sequencer with 3x remove magic increases your chances)
- summon hakeashar (better version of nishruu)
- Abi-Dalzim's Horrid Wilting is the best damage spell
- Incendiary Cloud (nice vs liches like kangaxx, he won't be damaged, but he will fail his spellcasting all the time)
- Pierce Shield
- PW:Blind
- Pro Energy
- Simulacrum (get a copy of you Kensai Mage that can cast and fight, with all your equipment copied too, that's one of the best spells, another Kensai/Mage for free)
- Spell Trigger (like sequnecer only better cuz it can hold up to lvl6 spells)
- Chain Contingiency (can contain up to lvl8 spells, use it in the same round as spell trigger to apply 6 spells of your choosing at once)
- Time Stop (stop the time then go nova or just start the chopping)
- Wish for resting (use convenient wishes mod if you don't like reloading until the rest option shows up:

- PW:Kill (damage a strong opponent a bit, quickly end the fight with PW:Kill)
- Dragon Breath
- Energy Blades (for pure mages very good, 9 attacks per round with -10 THAC0-> cast & attack)
- Improved Alacrity (gain permanant aura cleansing thus removing the 1 spell per round rule, cast cast cast nonstop)
- Summon Planetar (those planetars kick some serious butt with their vorpal blade plus they can take a beating too, the best summon)
