Anyways, these are all the items in the Alchemy Stone Shop or unlockables that you need to buy with it that I recommend:
- Skill Level Bead (the more, the better.)
- Every Character's 3rd Accessory Slot
- Refining Gems/Meteorites AT LEAST ONCE. (First time for Free not counted)
If anyone asked me why I didn't include the other two Plant/Bean Pots in the Farm is that... the Farm system relies on your phone's clock, so.... yeah (I cheated, yes.)
Anyways, for Skill Level Bead
- This is honestly the MOST crucial item on the shop. With it, your skill exp will grow at 3x rate inst6ead of 1 (meaning if you used one particular skill once in a battle, instead of +1 skill exp, it will become +3) and that's only for one piece of it. For two, it will become +5 and for three, +7.
For Free users, THIS should be the very first thing you should buy.
For Every Character's 3rd Accessory Slot
- This one is also crucial, unless you don't like Farming/Grinding for some items. At the start you won't particularly feel the great benefits, but mid-way through the game and especially at the end, you'll even ask for a 4th or 5th slot. I don't think I need to explain deeply, asit says - 3rd Accessory Slot. This can help you in every possible way, be it farming or blasting bosses up. It's recommended that you unlock every one of their locked slots, but if you really, really need to buy another thing at the shop and/or feel like your character's already okay anyways, you can skip this.
For Refining Gems/Meteorite:
- This is purely optional. But I recommend it nonetheless since Antiquia Lost is simply not the game itself. It's a gacha system similar to Asdivine Cross'... I forgot. Anyways, you can use 100 Alchemy Stone for a single try (although I do not recommend trying one at a time) for very good items. Rare items usually show up since they have 40% chance though.
The reason I recommend this one than the Weapon Refining one is that there a far too many useful stuff here. Although Weapons are also indeed useful, Skills and Gems are so much more, and the ones at the end of Tower of Rancor are good enough. If you have money to [strike]waste[/strike] spare, it's recommended to use 1000 Alchemy Stones for 11 Tries on both Gem/Meteorite and Weapon Refining.
And that's it. Although these are my recommendations, it doesn't mean that you should follow this entirely. If you want to use your Alchemy Stones for something else, like pot plants [strike]which I didn't buy since I can cheat it and I won't say how[/strike], go ahead. It's your money and/or hard work at grinding anyways.
