Why Speed Tuning Breaks Rotations
Speed tuning determines who acts when in the Action Value system. If your support acts after your DPS instead of before, advance-forward skills (Bronya Skill, Sunday) land after the DPS already wasted a turn. The result: fewer DPS actions per cycle, broken buffs, and inconsistent clears. Random speeds cause this.
Action Value Formula
AV = 10,000 / SPD Higher SPD = lower AV = acts sooner
Simple version: Get your DPS to 134+ SPD. Set your action advance support (Bronya, Sunday) to exactly 1-2 SPD lower than your DPS. Test in a real MoC stage and watch the turn order bar. Adjust from there.
Key Speed Breakpoints
| SPD Target | Who | Why |
|---|---|---|
| 134+ | DPS / most supports | 2 actions in the first cycle. Community-called "god breakpoint" - the standard minimum for MoC content. Below this and you risk losing a full cycle of damage. |
| 120-121 | Secondary supports | 2 actions across early cycles. Fine for off-supports or characters that don't need consistent turn timing. |
| 160-161+ | Hyper-speed supports | Acts so frequently they can spam advances/buffs regardless of DPS speed. Used in hyper-speed setups where DPS uses ATK boots instead of SPD boots. |
Step 1 - Choose Your Speed Strategy
-1 Speed Strategy MOST COMMON
DPS (134+) → Support (133) → Support advances DPS → DPS acts again
DPS at breakpoint, action advance support set 1-2 SPD slower. Support acts right after DPS and pushes them forward again immediately.
Best for: Bronya, Sunday, Sparkle, Yukong teams
Hyper-Speed Support
Support (160+) → pulls DPS regardless of DPS speed
Support runs at 160+ SPD. DPS uses ATK boots and stacks crit/damage instead of speed. Support pulls DPS so frequently that DPS base speed matters less.
Best for: Burst setups, SP-hungry teams, DPS with self-advances
Step 2 - Build and Test (In Order)
1
Equip SPD boots on the character being tuned
SPD boots are the primary source of speed. Choose flat SPD boots for the DPS, or SPD boots for the hyper-speed support if running that strategy.
2
Use relic substats and planar sets for extra SPD
Flat SPD substats stack well. Messenger Traversing Hackerspace 4pc gives bonus SPD and is popular for supports. Check which planar set your character uses.
3
Add a 1-2 SPD buffer for temporary speed buffs
Asta, Messenger 4pc, and other temporary buff sources can push a character over threshold and ruin turn order. Always build 1-2 SPD above or below your target to account for this.
4
Test rotation in an actual MoC or Pure Fiction stage
Check the turn order bar during battle. Note who acts when. Does your support act before your DPS's second action? If not, adjust relic substats.
5
Re-test after any gear change that affects SPD
Eagle of Twilight Line and DDD planar sets modify speed. Swapping any SPD-affecting relic means your tuning may have shifted. Always re-confirm turn order after gear changes.
6
Yukong special case: faster than DPS, buffs timed right
Yukong must act before the DPS, but her buffs only last ~2 turns. Make her faster than DPS but ensure her skill lands right before the DPS's attack window, not 3 turns prior.
Key Decision Points
SPD vs. crit/ATK trade-off - is it worth it?
For MoC and 0-cycling content: yes, hit 134+. SPD boots + substats cost crit/ATK/DMG, but consistent extra turns outweigh raw stat gains. For casual content, 120+ is sufficient.
-1 speed or hyper-speed support - which to use?
Use hyper-speed if your DPS has self-advances in their kit (they act out of order anyway) or you want max support uptime. Use -1 speed for straightforward breakpoint-based teams like Bronya/Sunday.
Should I farm for 160+ speed on my support?
Only if running hyper-speed strategy. For -1 speed teams, 134 DPS + 133 support is sufficient. Over-farming for hyper-speed is a significant time investment; most content clears fine without it.
My rotation breaks sometimes - what's wrong?
Check for: temporary speed buffs pushing someone over threshold, self-advance skills in a character's kit, or SP economy issues in double-advancer teams. All three are common desync causes.
Common Mistakes to Avoid
Random speeds with no tuning - inconsistent turn order every cycle. Even rough tuning (134 DPS, -1 support) is dramatically better than nothing.
No buffer for temporary speed buffs - if Asta buffs your support over the DPS's SPD, your advance lands after the DPS wastes a turn.
Over-farming for perfect 160+ speed - huge time investment. 134 breakpoint handles most endgame content. Only pursue hyper-speed if you need it for specific teams.
Not re-testing after gear swaps - any relic or planar set that affects SPD can break your tuned rotation without warning.
Ignoring SP economy in double-advancer teams - two action advancers (e.g., Sunday + Bronya) burn SP extremely fast. Build SP-positive characters to support this setup.
