Hero Promotion System
TLDR
Leveling the hero in Dragon Ball Super World Mission can be extremely tedious after level 50, so you may be wondering why you would.
First, the following applies whenever you reset a hero:
- Retain stats obtained from both bonding and comraderie.
- Unlock new abilities
- Higher base stats (haven’t confirmed)
Below is what you get for waiting to promote a hero at level 99:
- Additional stats (average of 9.6 points per level from level 66-99 on an early promotion).
- Max rank of abilities
Level 66:
- Starting HP: 2658
- Starting PWR: 3677
- Starting GRD:
Level 3 – Post Promotion:
- HP: 2613
- PWR: 3421
- GRD: 1699
Trial 2
Level 99:
- Starting HP: 3453
- Starting PWR: 4367
- Starting GRD: 2214
Level 3 – Post Promotion
- HP: 2754
- PWR 3537
- GRD: 1759
On average, about 9.6 stats per level was gained on reset over the 33 level difference. This is a total of 317 stats. There was about a 16.8-18.1% stat carry over without accounting for base stats. I believe this would in fact be closer to 20% when base stats are accounted for. In addition to that, level 5 or the max rank of abilities on most promotion tiers is unlocked at level 99.
