Information[]
Sen-Akhan is one of the 9 Outsiders in Clicker Heroes. Sen-Akhan increases the effectiveness of 
Dora.
| Level | Cumulative cost ( Ancient Souls)
|
Effect (Dora increase) |
|---|---|---|
| 1 | 1 | +100% |
| 2 | 3 | +200% |
| 3 | 6 | +300% |
| 4 | 10 | +400% |
| 5 | 15 | +500% |
| n | (n2+n)/2 | +(100n)% |
While it does take several Transcensions to get Dora to a level close to its maximum effect, below is a helpful formula you can use to find out how far a maxed out Dora will get you through the zones before Treasure Chest chance dips below 100% again, per level of Sen-Akhan.
Since treasure chest chance is multiplied by 0.994 every 500 zones, and Dora and Sen-Akhan's effects are purely multiplicative, you take -500 times the logarithm base 0.994 of their multipliers to get back to where you started, though this is adjusted with the floor formula. They will give 100+99n% chance for n Sen-Akhan levels, making the formula:
500*floor(-log0.994(1+0.99n))
Furthermore, the minimum Treasure Chest chance is 1%, so after you reach 100% chance, it takes 382500 zones, or 500*floor(-log0.994(100)), until chance goes back down to 1% and stops, although number logic sometimes makes this 383000 instead (actually replace the 1+0.99n with 100+99n for this).
The table below only applies if Dora is maxed out. If Dora is not maxed out, replace 0.99 by the appropriate number.
| Level | First zone with 100% chance | First zone with 1% chance |
|---|---|---|
| 0 | 0 | 382500 |
| 1 | 57000 | 439500 |
| 2 | 90500 | 473000 |
| 3 | 114500 | 497000 |
| 4 | 133000 | 515500 |
| 5 | 148000 | 530500 |
| 6 | 160500 | 543500 |
| 7 | 172000 | 554500 |
| 8 | 181500 | 564000 |
| 9 | 190500 | 573000 |
| 10 | 198000 | 581000 |
| 11 | 205500 | 588000 |
| 12 | 212000 | 594500 |
| 13 | 218000 | 601000 |
| 14 | 224000 | 606500 |
| 15 | 229500 | 612000 |
| 16 | 234500 | 617000 |
| 17 | 239000 | 621500 |
| 18 | 243500 | 626000 |
| 19 | 248000 | 630500 |
| 20 | 252000 | 634500 |
| 30 | 284000 | 667000 |
| 40 | 307500 | 690000 |
| 50 | 325500 | 708000 |
| 60 | 340500 | 723000 |
| 70 | 353000 | 735500 |
| 80 | 364000 | 746500 |
| 90 | 373500 | 756500 |
| 100 | 382500 | 765000 |
This shows that, while Sen-Akhan is extremely powerful in the early hundred thousands, it quickly loses its value, leading you to make a decision of whether to use it, or put up with the low treasure chest chance.
Usage[]
Sen-Akhan is a fairly important Outsider. While not as important as Borb or Chor'gorloth, it is able to boost your gold income by up to x100. Sen-Akhan boosts Dora, which doesn't scale very high or very quickly. However, Sen-Akhan's boost is the strongest of the Super-Outsiders, and Treasure Chest Chance does not decrease very quickly. For early-game and mid-game, you will want to keep Sen-Akhan at a fairly low level, because overspending does not give you more gold.
Eventually, past 24% TP, Sen-Akhan costs too much to maintain and is set aside entirely or mostly for the rest of the game.
Notes[]
Sen-Akhan was added to the game in Patch 1.0e10, along with Rhageist, K'Ariqua, and Orphalas.
Each of the outsiders that buffs an ancient is holding one of the platonic solids.
Sen-Akhan is holding the dodecahedron, which represents the universe as a whole.
