I’m currently playing STRANGER SAGA, and based on my play records, I’ve tried analyzing how its battle and stat formulas might work.
I hope this breakdown proves helpful to fellow players.
Damage Formula
Attacker’s ATK – Defender’s DEF = Damage
After progressing to Stage 5 and analyzing from my notes, this seems to be the confirmed formula.
Critical Rate and Damage Multipler
CRIT% is Critical Rate
Damage is multiplied by three.
Hit Rate Formula
Attacker’s HIT% – Defender’s AVD% = Hit Rate
This also appears to be almost certain.
Double Attack Check
If your SPD is even 1 point higher than the opponent’s, you attack twice. If it’s equal, you attack once. Double attacks also occur on counterattacks.
So far, I haven’t found any exceptions, so this seems consistent.
Healing Magic Power
Healing Amount = MAG
Aribel with 8 MAG always heals 8 points, so it seems the healing power directly references the MAG stat.
Formulas for HIT%, CRT%, and AVD% Stats
First, let me show the table. The sample data is taken after clearing Stage 5.
| Character | Class | Lv | HIT | SPD | LUK | HIT% | CRT% | AVD% |
| Bach | Warrior | 2 | 7 | 5 | 7 | 121 | 3 | 10 |
| Haino | Civilian | 5 | 3 | 3 | 2 | 109 | 1 | 6 |
| Ena | Civilian | 4 | 5 | 8 | 6 | 115 | 3 | 16 |
| Cellia | Civilian | 4 | 4 | 3 | 11 | 112 | 5 | 6 |
| Aribel | Healer | 2 | 5 | 3 | 5 | – | – | 6 |
| Felix | Archer | 2 | 9 | 5 | 6 | 127 | 3 | 10 |
| Anastia | Lady Lord | 1 | 4 | 5 | 6 | 112 | 3 | 10 |
| Regis | Soldier | 2 | 4 | 4 | 3 | 112 | 1 | 8 |
| Elissa | Griffin Knight | 1 | 6 | 10 | 1 | 118 | 0 | 20 |
Glancing over the data:
- Class seems to have no effect.
- There doesn’t appear to be any level-based adjustment.
- No character-specific modifiers are apparent, at least for now.
Based on this table, I’ll try analyzing Accuracy, Critical, and Evasion.
HIT% Formula
100 + HIT × 3
This explains all the observed values, so it’s likely the confirmed formula.
CRT% Formula
LUK × 0.5(fractions rounded down)
This also fits perfectly with all the data.
AVD% Formula
SPD × 2
Looking at the table under this assumption, all values match, so this seems correct as well.
Summary
Analyzing the formulas in an SLG really makes you feel alive!! Your skin practically gets that smooth, glowing effect too!!
I also put together my personal unit tier list—feel free to use it as a little side dish while you run your damage calculations.
I’m running a project called “IndieGame100”, where I play 100 indie games, including STRANGER SAGA, and write my impressions. If that sounds interesting, feel free to check it out.
And since I was really curious about why this game ended up being designed in such a compact way, I reached out to the dev, MST – san —turns out I even got the chance to interview him.
If playing STRANGER SAGA made you wonder about things like how MST – san first started making games, or what kind of anime he watches on a daily basis, definitely go check out the interview as well. I think you’ll enjoy it.
Alright then, enjoy your gaming life!!
Thank you for reading!
