TBS Damage Multiplied

TBS Damage Multiplied

A focused Forge 1.20.1 add-on for Torches Become Sunlight (TBS). It fixes only
confirmed player-owned TBS implementation paths whose fixed damage omits the
player’s active generic.attack_damage modifiers. The classifier is intentionally
conservative and is designed to leave vanilla combat, unrelated mods, native TBS
scaling paths, and unknown paths unchanged.

Damage model

For a confirmed fixed path, the original TBS amount D becomes a synthetic
attribute base. The player’s current modifiers are replayed in Minecraft 1.20.1
AttributeInstance order:

(D + sum(ADDITION))
* (1 + sum(MULTIPLY_BASE))
* product(1 + each MULTIPLY_TOTAL)

The player’s ordinary ATTACK_DAMAGE base is not used. Main-hand ItemStack
modifiers are controlled per operation by config; defaults exclude its ADDITION
and include its MULTIPLY_BASE / MULTIPLY_TOTAL. Modifiers from effects, armor,
Curios, relics, and other standard attribute sources remain. The live
AttributeInstance is never mutated.

Safety model

• Classification is by concrete damage implementation path, not weapon.
• Only ServerPlayer owners/casters can be multiplied; TBS bosses and NPCs are
  returned unchanged.
• Known native ATTACK_DAMAGE paths and unknown paths are always left unchanged.
• Narrow coremod hooks carry a stable path ID and target/owner provenance when the
  audited call site exposes both. A per-thread stack frame is consumed only by its
  matching LivingHurtEvent, then balanced after hurt, preventing hook + event
  double application without crossing nested damage calls.
• Ability-driven fixed hits are marked at their audited playerAttack -> hurt call
  sites; their path is never inferred merely from whichever TBS ability is active.
• Genuine left-click attacks are excluded because vanilla already calculated
  their complete attack attribute.

Configuration

The common Forge config is generated as
config/tbs_damage_multiplied-common.toml. Every fixed path has ordinary
ForgeConfigSpec.BooleanValue entries suitable for generic Forge config GUIs:

[paths.tbs.ice_crystal_hit]
enabled = true
addition = false
multiply_base = true
multiply_total = true
main_hand_addition = false
main_hand_multiply_base = true
main_hand_multiply_total = true

All fixed paths default to compatibility scaling enabled, with ADDITION
disabled. Main-hand ADDITION is excluded by default, while main-hand
MULTIPLY_BASE and MULTIPLY_TOTAL are included by default; each can be changed
per path. General settings provide a master switch and opt-in path-oriented
diagnostics.

The Rosmontis Embrace player assist path retains its original fixed 16F as
the base and only replays MULTIPLY_BASE / MULTIPLY_TOTAL; ADDITION is
always ignored for that path because the fixed skill value already represents
the complete skill base.

Audited target

The integration and exact coremod call sites were audited against the local
torchesbecomesunlight-0.5.0-hotfix2.jar (whose embedded mod metadata reports
version 1.20.1-0.4.2). A future TBS bytecode change deliberately fails the
affected transformer loudly instead of silently patching an uncertain path.
