Shock

Shock

Lightning is the school of hits that jump between enemies and of short stuns. Every hit of a lightning spell can shock its target.

Shock chance

Chance per hit = base chance of the spell + your Shock Chance, at most 100 %. Each hit rolls once.

Spell	Base chance
Spark	10 %
Lightning Bolt	15 %
Chain Lightning	20 % per hit
Lightning Nova	always
Static Shield (counter-strike)	50 %
Lightning Strike	50 % per target
Thunderstorm	25 % per hit
Storm Elemental (its Lightning Bolt)	15 %

• The base chance is part of the spell file (marker stormcaller:shock/<percent>, see Changing spell values). The spell tooltip shows it as "Shock chance: 15%" or "Always shocks."
• Lightning damage of other mods (damage type spell_power:lightning) can shock too, but only with your Shock Chance. It rolls at the end of the server tick, so a hit never rolls twice.
• For summons (Storm Elemental) the Shock Chance of the owner counts.

The Shock Chance attribute

stormcaller:shock_chance ("Shock Chance") is a new attribute. It works like the Spell Critical Chance of Spell Power: base value 100, items add to it as a multiplier (0.02 = +2 %). The tooltip shows it as "+2% Shock Chance".

Source	Shock Chance
Lightning Robe (tier 2), per piece	+2 %
Netherite Lightning Robe (tier 3), per piece	+3 %
Fulgurite and Stormweave Robe (tier 4), per piece	+4 %
Stormweave Robe, set bonus (2 pieces)	+5 %
Stormheart and Thunderstrike rings and amulets	+3 % each
Static Charge (Static Lodestone)	+5 % for 6 s

What a shock does

Shocked (every target)

Every shock gives the target one stage of Shocked:

• +5 % lightning damage taken per stage, up to 5 stages (+25 %).
• Lasts 8 s; every new shock adds a stage and refreshes the duration.
• Only damage of the type spell_power:lightning is increased, other damage is not. The hit that shocks is not increased yet, the next one is.

Stun (normal targets)

Normal targets are also stunned for 0.5 s (spell_engine:stun). The stun does not stack; a new shock only makes it longer if the new duration is longer. Lightning Nova always shocks and stuns for 1.5 s.

Slow (bosses and players)

A stun switches off the AI. Bosses with fixed attack patterns can get stuck by that, and many fast hits could hold a boss in place. So targets in the entity type tag #stormcaller:shock_resistant are slowed instead of stunned:

• 50 % slower for 1 s,
• then 3 s cooldown before the same target can be slowed again (stages of Shocked still stack in that time),
• their AI keeps running.

The slow is the effect Shock Slowness (stormcaller:shock_slow).

#stormcaller:shock_resistant contains #c:bosses, #mrpg_lib:stun_immune, the Warden and the Elder Guardian. Packs can add more.

Players are slowed like bosses too, not stunned (option stun_players).

Stun pause

After a stun from a shock ends, the same target can't be stunned by shocks again for 2 s (option stun_pause_seconds, 0 turns the pause off). Shocks in that time still give stages of Shocked, but no stun, and they don't make a running stun longer. The pause is stored on the target, so it counts for all players together. Lightning Nova always stuns, also during the pause, and the pause starts again after its stun. Stuns from other mods or commands are not changed and don't start the pause.

This keeps big single enemies from being locked down: on tier 4 a normal enemy with a lot of health was stunned about 40 % of the time before 0.3.0, now at most 0.5 / (0.5 + 2) = 20 % with the default values.

Targets in #stormcaller:shock_immune get nothing at all: no stage, no stun, no slow. The tag is empty by default.

Looks

Shocked targets show small lightning arcs on their body, more often and stronger with every stage.

More shock

• Skill tree: Conductive Chain (Chain Lightning rolls twice), Thunderclap (Nova stun +0.5 s), Charged Roll (next hit always shocks), Storm Ward (melee attackers may be shocked). See Skill tree.
• Stormbringer Staff: its passive Skyfall triggers on shocked enemies. See Equipment.
