changes in bcrawl
For a full list of changes from DCSS in bcrawl, see the readme.
For some particularly important changes for this tournament, see below.
gameplay
Dungeon is 12 levels deep; Lair branches (Swamp, Snake, Shoals, Spider) and Vaults are 3 levels; Orc is 1 level.
bcrawl has no exploration trap effects.
When taking stairs there's a 4% chance of being teleported onto the lower floor.
When in Zot or carrying the Orb, instant teleports (from stairs or traps) are replaced by blinks.
With at least 1 bar of spell power per spell level, transformation spells last until ended.
species
Demigods start with a self-god with several active abilities.
Vampires can only use Bat Form when full or above, and still regenerate when bloodless.
Felids get half XP for seeing enemies, and no extra XP for killing them.
Sand Dwarves are slow, small, and have no body armour penalty to spellcasting.
Tengu and Deep Elf are merged into Avariel.
backgrounds
Sloth Apostle starts with a shield and Cheibriados.
Artificer and Assassin are merged into Rogue, which starts with both needles and wands.
Skald starts with Ozocubu's Armour and a fear scroll. Infusion scales better with spell power, making it viable longer. Ozocubu's Armour only lasts a few turns, but doesn't break when you move and freezes enemies that hit you.
Arcane Marksman starts with Corona, Shackle, Inner Flame, False Image, Cause Fear, and Yara's. Corona is buffed. Shackle prevents enemy movement. Inner Flame always works. False Image creates a decoy you can shoot through. Yara's is level 4.
Venom Mage starts with Sting, Poisonous Vapours, Ignite Poison, Olgreb's, Summon Scorpions, and Venom Bolt. Sting is buffed, always poisoning on hit. Poisonous Vapours lasts longer at high spell power.
Reaver starts with melee skill, steam dragon scales, and Vehumet.
gods
Dithmenos loses Shadow Mimic. Instead, Shadow Step is cheap, and creates a ghost of yourself for a duration that depends on Invocations.
Fedhas piety comes from kills. Fedhas abilities use piety instead of rations.
Nemelex has bigger max deck sizes, and Triple Draw doesn't cost piety.
Wu Jian's Serpent's Lash ability costs drain instead of piety. That drain cost decreases with piety. Heavenly Storm is cheaper but has a lower initial duration (which means a lower slaying bonus).
Sif Muna has faster piety gain and gives book gifts earlier.
Uskayaw's Line Pass ability doesn't cost piety.
