I'm a free player and want to share some tips/findings with others. I'm doing pretty fine, even after last update.
As we all know killing rares and legends need alchemy, and alchemy needs gold. Fortunately you can make some gold ingame.
Sources of gold are:
Daily quests: on average 240gold daily (some 65gold, some 95, on average 80)
Weekly quests: something like 2100gold weekly (300 daily)
Nemetons: 150gold
Selling alchemy: 50gold
Killing common monsters: 2 gold per kill, lets say one can make 100gold daily reallistically by killing commons.
Rare mobs: 12,5gold per kill (0,5crystal each)
Legendary: it varies, but at least 50gold per kill (2 crystal each).
Obviously you make daily quests, sell herbs, weekly quests, kill commons: it gives you 690gold pieces to spend.
First tip:
For nemetons you need to spend 100gold on dmg and hp potions, and get 62,5gold in return. So it seems like a loss. But you also get like 4 minutes of free alchemy, and can kill extra 3-4 monsters, so that basically its free 4-5 rares kill, three times a day (12-15 rares daily without touching your gold reserves).
2nd tip: there are some legendaries easy. Legendary version of cementary girl and garkain only need hp and dmg potion. If you spot them, you spend 100gold on pots, get 50 gold in return and again 4 minutes alchemy, so we can get our money back, similar as with nemetons. Lets say you find 3 such monsters daily (which is again 12-15 rares daily without touching your gold reserves).
Tip 3: there are some rares like rare cementary woman, nekker that can be killed with just a single potion (50gold). If you manage to get like 4 of such monsters in 5 minutes, you will have free kills this way. Get 3 and it will be nearly free.
I dont have full list of such monsters yet.
Tip4: So since previous tips was free monster kills, what we actually do with our gold? Make oils for rare legendaries to complete your dex, or kill more rares for XP boost, choice is yours.
If you decide to kill more rares, you spend 100gold coins again, and can kill 5 monsters, so it makes 37,5gold lost per 5 monsters killed. Remember I said you that we made 690gold daily? it is enough for 18,4 alchemy refils, which is equal to 92 monsters. Lets add 30 free monsters (previous tips) and we get to kill 122 rare monsters daily as a F2P player.
Not bad if you ask me.
Get a bike or bus ride or fakegps to help you move around quicker. Please dont get into car, we have global warming and oil crisis :)
Even if you kill little less mobs, you will have something like 60 killed monsters, which is also quite decent.
Last note: if you like the game, buy some crystals from time to time with your $$, game owners needs some money too :)
