So, I'm about to tackle ice queen with a drakeling, to be more precise the barbarian prince.

After one emarrassing death, my recent drakeling quaffed 4 blessed potions of speed and it did the trick, this time it seems I got one potion of speed, no alchemy.
I can deal with most stuff but afraid of the speed 10 death.

Any other tricks to boost speed?
I've got 2 boost dexterity potions I guess that would get me a small increase.
Fireball traps in the trap area can be used for a small increase but it may very well be gone 2 rooms later.
