Okay, I'm making progress now.  I've killed 4/28 of the wizards and have 5 attack and 10 strength, so I can hit 2's and don't miss as often.  I was having to basically collect an entire inventory of cookedmeat to kill one wizard, but now I think I can manage 2 kills per inventory, and that should go up quickly as I level.  Wish I had started on a chicken task...

Hey guys, glad I got some interest! I think you're right about the runes, it shouldn't be necessary.  I've only bought about 30 wind strikes and I didn't even need it to kill my first wizard, since I killed the second one with melee alone, so I might just stop now going forward.  As for food we'll see. It also depends on how quickly I can get to 37 prayer for paralyze monster.

Are you restricting yourself from all store bought items? as with your current ruleset you could just buy out bronze bars from the store to level smithing slowly, anyway goodluck, sounds like a fun snowflake

Yeah, I'm currently only planning on leveling production skills if I get all the supplies from slayer kills, so I'd only be able to get any smithing levels if I somehow got copper and tin ore drops.  Even if I leveled it, it would just be for total level because I'm not allowed to equip anything that wasn't a drop.

Cool. I agree about the runes. I don't know enough about the food situation to see whether it is feasible or not. Possibly, as slayer levels slowly, so you may be overpowered for some tasks.

Yeah, that's one thing I'm worried about, it might just become too easy as my combat levels outpace my slayer tasks.  My gear will be pretty bad for a long time though.  Maybe I should have done Veteran mode too hahah

Sounds great!

I Wish you best of luck on this account, and hope to read more updates in the future!
(I've wanted to make an account like this as well, in fact I had already created it with the release of slayer ).

Update #2! I finished the bears with little trouble, having to restock on food about every 4 at first.  Cooking the bear meat sped up restocking on food, and as I leveled, I was able to kill 8-10 with an inventory of cookedmeat.  I ended the bear task with 17 Slayer, and also reached 18 cooking with the bear meat.

After the bear task, I decided to update my rules.  Here are the main two differences:

1. I CANNOT pick up any inedible respawning items.  This is to disallow money making methods like picking up steel platebodies and staves of earth in the wilderness.  I can pick up things like cabbage, cookedmeat, or even the stews on the floor in underground pass if I make it that far, but nothing I can't immediately eat.  This also restricts things like grain, that can technically be made into food, or anything raw that might respawn.
2. I CANNOT buy items from shops.  I don't think it's necessary to buy runes or food, so it seems like more fun to just cut out shop items entirely.  I can still sell stuff though.

These rules, just as the rest, are subject to some exceptions and potential updates as new challenges arise.  One exception immediately became obvious once I got my next task...Desert wolves.

It's pretty clearly impossible to reach desert wolves without buying a shantay pass, so I'm allowing myself to buy those.  Luckily, I still have a little cash from selling my starting gear, but I think I'd have to make some sort of exception if I get a desert task and have no cash to buy passes.

For each trip, I stocked up to 29 cookedmeat, then bought a shantay pass and went to kill the one desert wolf just south of the shantay entrance.  I was at first able to kill 3-4 per trip at the beginning of the task, but that moved up to ~5 per trip near the end.  The task left me with 19 Slayer, but it also got me to 40 combat, which unlocks the varrock task master!

One disappointing thing about the tasks I've gotten is that none of them have provided me with any gear that gives weaponAim, weaponPower, or Armor.  I've been literally punching bears and wolves to death in a chef's hat and wizard robes.  Hungry for a gear upgrade, I decided to risk taking a task from the Varrock slayer master, and I got Monks of Zamorak.

I was excited at first, because the RSC wiki says that the level 29 monks of zamorak drop a steel mace! This would be my first legitimate weapon.  Unfortunately...on this server, only the level 47 Monks of Zamorak drop the steel mace, and those are in taverly dungeon, behind the dusty key door, dragons, and black demons.  I DEFINITELY can't make it to them, so I decided to just punch the ones at the chaos temple to death instead.

This task was pretty easy, since the monks are now aggressive if you're on a slayer task for them.  The task got me to 21 slayer, and the bones got me to 18 prayer.  I wasn't expecting any drops, but I actually ended up getting a Zamorak Robe top. The 3 prayer bonus will come in handy down the road.

With 20 Slayer, I decide to get a task from the Falador master, since it'll probably be safer than the Varrock master.  Once again, I get a task with no gear drops...Unicorns.  That's where I'll end this update though.  Thanks for reading, so happy to see the attention this idea is getting!
