About this project
What does Tempo Not Time add?
Tempo Not Time
Tempo Not Time is an addon for Iron's Spells 'n Spellbooks that reworks how you spend and recover between casts. Instead of watching a mana bar drain and refill over time, you manage a small pool of charges per spell and a shared casting reserve that fills back up as your cooldowns finish. Iron's spell costs, cooldowns, equipment bonuses, and all addon content stay as the balance source — Tempo Not Time just changes what that spending means in play.
Think of it as: you still pick the same spells, but the rhythm of casting shifts from "wait for mana" to "juggle what's recharging."
What changes
- Casting Reserve — Iron's Max Mana becomes a shared reserve pool. Active recharges hold onto a portion of it until they finish, so spamming everything at once has a real cost.
- Spell Charges — each spell gets a number of usable charges based on your reserve and the spell's cost. Spent charges recharge independently, so you can fire a few quick shots and keep going while others recover.
- Cooldown Load — the more spells recovering at the same time, the slower they all recharge. Fewer active cooldowns means faster recovery. This keeps burst-casting from feeling free.
All three systems are independent — you can run any combination, or flip the master switch off and get Iron's normal behavior back.
How it feels in play
- Your mana bar is now a Casting Reserve meter. It drains as recharges occupy slots and refills as they complete.
- Spell-bar icons show a charge count when more than one is ready.
- Cooldown shading still tracks the next charge coming back.
- Tooltips show your effective recharge time, including any cooldown-reduction bonuses.
- Recharge durations are gently normalized so a 0.5 s spell and a 12 s spell both feel like they recover at a reasonable pace relative to each other.
- Equipment, curios, potion effects, and upgrade modifiers all still apply to your numbers.
- Death, logouts, and dimension travel don't wipe your progress — cooldowns keep ticking where they left off.
Configuration
Server-side gameplay is configurable (reserve bounds, charge limits, load penalties, recharge normalization, per-spell overrides, and more). Client-side presentation follows Iron's existing mana-bar display settings, so anchor, offsets, and text style carry over.
Per-spell tweaks are supported via a simple override file — any spell not listed just uses the calculated defaults. A single command (/temponottime reload) picks up changes without a restart.
Admin commands
All require operator level 2:
/temponottime info— overview of current state/temponottime reserve— show reserve details/temponottime cooldowns— list active recharges/temponottime charges <spell>— inspect a specific spell's charges/temponottime clear— reset casting state/temponottime reload— reload config and overrides
Compatibility
- Built-in and addon spells work as-is; no per-spell compatibility list is needed.
- Player casts from spellbooks and magic swords are fully managed. Scrolls and mob-cast spells keep Iron's original behavior.
- Iron's own attributes remain intact internally, so other mods and addons that read them continue to work.
Tempo Not Time is a fan-made addon. It is not affiliated with Iron's Spells 'n Spellbooks or its author.
