NPC bit flags

Bit flags are special traits that can be programmed into NPCs to give them certain abilities. Most of these bits are listed in the help_npc.txt file in the user folder, under BitOn, which includes instructions on how to use them for the creation of custom NPCs.

The game's own original NPCs already have their bit flags hard-coded, but these can still be modified (via EloSnack or memory editing). Values for ingame bit flag modification are listed under the "Ingame ID" column.

Note: in Elona+ version 2.08 on, every character's bit flags are now listed in the "Feats and Traits" window. 2 new bit flags not currently on this page were added in that version.

Primary bit flags

Standard bit flags, available to both original and custom NPCs. Bits 0 through 4 are reserved for temporary in-memory operations. The first 32 of these are stored at offset 1800 in cdata.s1, and the next 32 begin at offset 1804.

Floats the NPC. Among other things, it saves them from acid pools, deaths when drinking from wells, and triggering traps.
cInvisi	6	Any	64
The NPC is invisible. They can only be seen by the player when they are wet, or when the player has an item that lets them see invisible creatures equipped. NPCs with the cSeeInvisi bit can still see them. A pet that is invisible will still be seen by NPCs, regardless of the NPCs' ability to see invisible creatures.
