What would be the cheapest way, SP wise, to get an Angelic pet?

Wait for your loyalty box and use the potion in it would be the absolute cheapest

This one's a toughie. Angelic Potions are hard to get ahold of. Spam the Potion Lottery-the price of all of the tickets is small compared to the cost of the potion maybe? Stalk the Adoption Center? Try for a Trade with an item you just happen to have that's on someone's wishlist?

Yeah, a loyalty box might be wisest. However, you have to be patient. You get one your second year on Subeta and every year following. Keep an eye out in the giveaway forums. I once legitimately won an Angelic Potion in a giveaway where a random user post was selected. Adoption Center is also a good idea. If you see an Angelic pet you like, snatch it up. You can change it's name and gender for much cheaper than getting an Angelic potion. Another strategy is to zap the pet you want Angelic. Every time its species changes in a zap, buy an elixir to change it back. Both Zappers are in Darkside, and cost a couple Wizard tokens. The Potion Lottery... Lol, I only ever won it on an ooooolllld account of mine that was wiped. You just need to get lucky there. Or break down and just buy one with sP or CSC.

I wasted an assload of sP on my Angelic pet, and now I don't care for her much. vnv

it is not possible to zap Angelic.

Ah, figures. xD Of course. That'd be too easy, eh? Scratch that then.

I think the quickest way to get one is to just spend the sP or CSC, really. It might be wiser to sMail a user and get a good deal on one.

I bought one back in the day when it was about 20m, I don't recall ever zapping a pet angelic. Angelic potion is selling for 40m sP today, you may be able to haggle in trades for 35m. Or you can buy for 1,500 csc. I believe 100 csc exchanges to 3m sP, so 1,500 csc = 45m sP. Buying with sP would be cheaper than csc.
