Sleepywood-locked Challenge

I got this idea from another server and from what some people are doing on oldschool Runescape.
The challenge is as follows: at level 20, you must move your character to Sleepywood. You can bring 1 clean weapon that you can equip at that point and 5,000 mesos but no other items whatsoever, no usable items like potions or scrolls nor equipment nor ETC items. An exception is made for thieves, archers, and pirates, who can bring ammo, and chairs are allowed as well.
After this point, there are 3 rules:
1. Do not leave Sleepywood, ever. The allowed area is defined by the following map:

Exception: you may leave to job advance only
2. No trading, except to other people doing the challenge. Don't give items to your character from other characters, either. Don't take items that other players drop, and don't use your alt to farm items for your character.
3. No leeching or using buff mules.

We have a small group playing so far:
Proserpina (me), TM28, and KungSku

 

Job advance is allowed.

 

Spoiler: Quiet meditation before the fall

Spoiler: IT BEGINS!!!!

Spoiler: Introducing the 2nd spelunker, TM28!!!

Spoiler: I bought 44 eggs but forgot to get mana potions!!! oAo

Spoiler: Potions are expensive and money is hard to come by, but somehow, it works out

Spoiler: First level in Sleepywood! There are no LUKless wands down here, so I must add LUK.

Spoiler: 2 more levels, a pair of boots from KungSku, and a Pan Lid!!!!

The biggest hurdle so far has been making money for potions. I'm constantly on the brink of bankruptcy.

The 2nd big challenge is figuring out what job and build I want to go with. LUKless is always an option, but down here, I'm at the mercy of my luck (or lack of luck, in this case) when it comes to Gachapon and event drops. Otherwise, base LUK must be added.

I'm torn on what 2nd job to go with-- I/L mage has a very nice AOE option, but Cleric has much more utility. Maybe a battle Cleric build with Holy Arrow max is in order!

 

I didn't know the regen rates were different tbh....

 

I would sacrifice heal because I'm not gonna train on Zombie Mushrooms after level 30 and otherwise it's not too important to have it maxed.
