Changelog

1.0.0

First release.

Thunderbrand versions of every vanilla mace, club and sledge, forged from the plain weapon plus Thunder Stones and Eikthyr's trophy.
Lightning damage on top of the weapon's normal damage, and an electric glow, crack pattern and arcs fitted to each head.
Spark trail on swings, lightning cracks and sparks on hits, enemies visibly shocked.
Secondary attack (middle mouse): the overhead smash calls down a bolt of lightning where it lands. It wins over other mods' special attacks on the same button. The two-handed maces (sledges) use the Flametal Sledgehammer's secondary, together with a matching main attack and hold animation, so both mouse buttons play (TwoHandedSecondaryFrom, TwoHandedMainAttack).
Throw and recall (F): the mace flies out, strikes where it first lands and flies home on command.
Lightning leap: jump with a Thunderbrand in hand to bound high into the air, trailing arcs and sparks, and land with a strike.
Soft, sparse electric cracks on your armor, cape, shield and skin (the gear's own colors stay visible), arcs crawling over your body and a crack of lightning when you draw, all while a Thunderbrand is held.
Round shields share one size; shields on your back clear your cape; blocking with a shield while holding a Thunderbrand shocks close attackers a little.
Every Thunderbrand has exactly one recipe and one name in the crafting menu; the mod checks for repeats and removes them.
Everything is shown to other players who run the mod.

Some two-handed maces (sledges) do not attack properly: their left-mouse or middle-mouse attack may not play or may swing the wrong attack, mostly alongside mods that change the sledges' attacks (such as Therzie's Warfare). Options under Secondary (TwoHandedMainAttack, TwoHandedSecondaryFrom) can help. One-handed maces are not affected.
