So since I've not yet found a Seed guide anywhere I'll post my start here, haven't dived too deep into Endless yet as that seems a damn slog without farming for a few more Abilities but it might help someone for now
Also adding some Tips I've found on the way.
Stage 1
Zombie | +5 ATK | -1 AGI |
Zombie Dog | +1 AGI | -50 HP |
Bloat Zombie | +50 HP | -1 AGI |
Cyborg | +10 SP | -2 AGI |
Licker (???) | ??? | ??? |
Stage 2
Chomper | +5 SP | +1% Damage Received |
Anaconda | +5 ATK | +1% Damage Received |
Ivy Zombie | +5 ATK | -5 SP |
Freeman | +5% DMG Hand Grenades | -2% HP |
Stage 3
Derivative | +1% HP | -1% Crit Chance |
Failed Subject | -1% DMG Taken | -1 AGI |
Disguised Subject | +5 SP | -50 HP |
Jackman | +1 AGI | -5 SP |
Stage 4
Nurse | +50 HP | -1% Crit Chance |
Lizard | +1 AGI | +1% DMG Taken |
Drone (Manager) | +1% Crit Chance | +1% DMG Taken |
Gatekeeper (Manager) | +1% Crit Chance | +1% DMG Taken |
Stage 5
Bodyguard | +10% Sensitivity when fucked from behind | |
Captain | +2% Firearm DMG | +1% DMG Taken |
Knight | -5% DMG from Animals | -1 AGI |
Each Seed can be taken 10 Times, just beware that the Drone and Gatekeeper are the same Seed.
The Magnum can be gotten from the Licker enemy in the first level in a side room if you repeat the level later, I believe you have to beat level 3 for him to spawn but don't quote me on that.
The SMG can be gotten by Talking to the Guy at Stage 20 of Endless, after that fighting Pyramid Head on one of the Boss stages and then in another run bringing the Wig he dropped to the guy on Level 20 if what I read is right, haven't done it myself yet.
You advance skills by getting fucked and cumming, don't be like me and not make use of that until late in the game, there is no achievement or special treat for getting through the game as a virgin.
Especially nice is the skill to steal from Enemies, it's a pretty late one and takes some time to get but you got a 50% Chance each encounter to steal something from an enemy if he fucks you, it can drop Skill Upgrades.
The Final boss in Stage 5 seems to never fuck you (Which makes sense storywise) so he has no seed but he drops an Apple, all three Stat Fruits and 3k each time you kill him.
If someone has the stats for Endless or the Licker (???) enemy from the first Stage which I've never found again after my first time I'll gladly update the chart, else I might do it tomorrow myself.
