Finally obtained with my mummy chaos knight of Lugonu a way to get to Abyss without being having to use the power : by killing Sonja and wielding/unwielding her dagger of distorsion.
And with some luck i found a Lugonu altar very near, and my giant mace was branded.
Additionally, i found a few nice scrolls to enchant it further :
- a +3,+6 great mace of distortion (weapon)
What a very powerfull it is now, if an enemy is more powerfull than my character and can't be killed quickly, lots of chance the brand will either teleport it away or banish it to the Abyss, and even if unlucky the weapon does not kick the enemy out of the view, it can have some good damage bonus with this brand : my mummy have 2 shot-ed several hydras in my exploration of the Lair.
And talking of Lugonu, i noticed with a mummy chaos knight you actually get faith ranks rather quickly, as you don't have to eat, you can sacrifice everything you kill (you get faith from kill+faith from sacrifice), meaning you can get the highest Lugonu faith rank before Lair (as a chaos knigh you start already with this faith if you choose it so you gain a lot of time beginning to earn faith points right from the start of the game).
Corrupt is then rather quickly available to you, and it's definitively a very powerfull help.
I just got the Swamp rune thanks to it, the bunch of neutral demons that comes from the corruption can make short work of hydras and dragons (and a good weapon of distorsion will annihilate the survivors)
Corrupt helped me too in a dungeon floor in which there was a bit too much Ogres near the stairs.
Very fun to play such combo. I'm not sure if the increased GDR (from the website it is apparently doubled in 0.
helped a lot, but as i have some very good armor items, with AC 33 currently, it can help the survival of a melee oriented character too.
Though, it seems my mummy is a bit too powerfull and lucky until now, it certainly means Crawl will find a way to kill it soon.
