Mostly-fresh newbie here. Enjoying myself so far, but I have two questions that need more than wiki-skimming to answer:
1. What a good way to find someone to trade sprite food with? I've suckered one of my friends into playing and they picked a different sprite, but I can't figure out a decent way to find someone to trade the 3rd kind with. I feel pretty silly pinging Trade every minute or two with "WTT motes!" when everyone before and after me is selling/trading stuff so powerful and expensive I'm not even certified to look at it.
2. How fast should I expect to be forging my gear up? Currently rank 4-2 and sporting a full set of 2-star gear, mostly running tier 1 stuff (rank missions or via the arcade) and I usually forge everything at 3x because I'm on to you, RNG. Most of my gear is level 5 now, which demands 9 crystals per 3x forge, but I only find that many crystals in 1-3 runs, so I'm barely forging anything up. Would I be finding more crystals if I ran tier 2 stuff? Am I expected to buy more out of the Trade Depot with Energy? Or is this about the normal grinding speed?
Catch-all disclaimer: emphasis on newbie, and mostly casual to boot. Mostly keeping to myself though.
Tangent: WOW this game has a nice wiki! Absolutely wonderful for reading junkies like myself who like to spend a few hours RTFMing.
I've traded a lot of sprite food in Haven, by just asking for trades over ordinary chat. But that has mostly been 5-star food. I've also traded with guild mates. Are you in a guild? Your guild should be running a trading scheme.
Forging is a relatively recent addition to the game (since 2013-07-30). The key things to know are: You don't need to forge 2-star items at all, to upgrade them to 3-star. You want to forge 3-, 4-, and 5-star items as much as possible, at 100%, to get Forge Prize Boxes. 5-star fire crystals have become quite rare, so it is difficult to heat 5-star items. 5-star armor at heat level 1 is often as powerful as 4-star armor at heat level 10, but the same cannot be said for weapons. So upgrade weapons to 5 stars only when you have enough 5-star fire crystals to get them at least to heat level 5. You might want to read the wiki page "Rarity". I'll leave your other forging questions to other people.
I'm glad that you're enjoying our wiki. It's not perfect, but we work on it. Feel free to ask more questions here.
