UltraItems is a custom-items plugin for your Minecraft server (Purpur 1.21.1x). Vanilla weapons only swing and hit — these items do things: fire lightning, encrust enemies so they can't build, hurl lassos, summon orbital strikes, heal you on kills, and more. Everything you'd want to know:

The menu — run /ultraitems menu to open it (OPs only). Items are grouped into tabs: Swords, Axes, Bows, Legendary Items, Other, and Admin Items. How items work — take one from the menu and it's just a normal item in your inventory. Read the colored lore; each line explains the ability, its effects, and its cooldown (e.g. "Every 3 crits: victim is Encrusted"). Cooldowns — most abilities have a cooldown shown in the action bar while recharging. /ultraitems cooldown clears your own. Legendary items — a special tier that levels up with you. Kill/use the item enough (15 kills + 15 uses) and it strengthens — better stats, stronger abilities, plus an aura while you hold it. /ultraitems tier <Regular|Strengthened> sets the tier. The resource pack — when players join they're prompted to accept a resource pack so these items get custom textures, models, and sounds instead of looking like vanilla tools. In short: it's a toolkit that turns normal Minecraft combat into a game of special abilities, and /ultraitems is the one command that drives it all — menu, give, cooldowns, tiers, and the admin TNT-rain command.
