I've made a mod of Shattered Pixel Dungeon, Called Xun's Pixel Dungeon.
Currently only Chinese is available, but anyone who is interested in helping me translating it can leave comment here.
Sorry for poor English >_<
Main Changes:
Equipments:
Many new weapons (including tier 6);
Tier 6 armor;
Each 2 new enchantments/glyphs and 1 new curse for weapon/armor;
A new Wand which works like the wand of avalanche in originalPD, but has changed logic;
A new Ring which increases hero's vision radius;
A new artifact to replace ring of elements, which works like unstable spellbook in potions;
7 new trinkets;
A new extension bag used to hold foods;
Consumable items:
5 new bombs;
4 new brews, 6 new elixirs;
11 new spells;
Gem powder, which works like arcane resin in rings;
Adventure:
2 new hero classes: Explorer and Wraith!
5 new challenges;
Developer mode;
Some new Badges.
detailed change log: check Changelog.txt in Github releases.
Things like this could be really cool, but I think it still should be counted as 0 chal in rankings. After all, you may just turn on all 9 chals when Yog fight is going to end, and then "Win" a 9 chal game.
