The thing is to win the second you have to save Whupaz. And the best way I've found to beat Chzar without it is two salves, a mid fight level up and a chaos avatar. Additionally I scum for the dwarves gauntlets (although they're not necessary to beat Chzar sans Whupaz) because you need them for stage 3. Frankly, I might switch that and prep the gauntlets simply because they are great for the second phase. What I prep other than the locker is pretty standard. Black market, extra altar, magnet: fireball, perserverence badge, compression seal, Whupaz, salve, and the two standard potions (although I should probably switch the health potion for a reflex tonic). Frankly, without Whupaz for Chzar you need all 3 corrosion wipes for the fight (two salves and chaos avatar).
@Waldo0: The numbers are totally blurred for my moniter, but I assume you had troll heart/dwarves gauntlets and another hp giving items. Also, I thought you meant that there was another goblin AFTER the others. In that case this is definitely doable. I'm curious to here what you're prepping and your strategy...
Here's what I do:
Pt 1: I start by BURNDAYRAZing level 1s to get off the ground without getting ruined by corrosion. Then I stick to 2 BURNDAYRAZ 1 hit kills until I am just short of level 6. I fight Chzar by using a mid fight level up, then chaos avatar, then regen fighting. At 2/3 hp use the first salve, then the next salve when he has 1/3. You practically need MW for the boss fight. Before you exit, make sure you have some way of hitting first and as manny damage boosters as possible.
Pt 2: I don't kill and swamp totems, but instead use my boosted damage and first strike (or monster slowing) to level up. CYDSTEPP is a great find. At level 6 or 7, when you are out of exploration and just short of a level up, Whupaz the boss, break all 3 totems and level up. Then use BURNDAYRAZ and any attacks to beat his remaining 750 hp. TT is a nice find. If you use him, save a reflex quicksilver combo for Bleaty on the next stage.
Pt 3: I have only gotten here once (I tend to restart a lot instead of wasting time when I know I can't win), so I don't know if the bosses are always the same, but I'll assume they are. Level up as much as possible using the whole map, then start the boss thing. Try to be set up for a mid fight level up. Depending on which potions you have less of (probably mana) pick a target to level up kill (ideally tormented one or Jörmungadnr) and use remaining monsters and/or Bleaty quicksilver+reflex combo to mid fight level up kill. If I remember that leaves Jörmungadnr, Iron Man, Gobb, and the Tower. You should hopefully be able to regen fight the iron man (Gauntlets+charms and gems for enough damage). You'll have to potion out the rest of them. Level off Jörmungadnr if possible, and if you get a viper ward you can regen fight him you can regen fight him instead.
If that helped anyone I'm glad, but more importantly, I'm curious as to what anyone thinks of the strat(s) and if/how they can be improved.
I speak chaos.
