Re: Aegis Thousand Year War - DMM Online Game
It depends. Every additional fairy multiplies the experience multiplier. If you are feeding a unit a fairy that is a different grade, then the multiplier is 1.5x. Otherwise, if it is the same grade, then the multiplier will be 2x.
If you are feeding a unit levels 35 or higher, then 2 bronze + 2 fairies or 1 bronze + 3 fairies are cost efficient if you can farm the fairies frequently. This is important because it is costly to continuously feed low grade, low level units to a high level unit. It can be as much as 2,000 gold a unit to feed for a unit in the 40s. If it takes 2 sets to get a unit leveled up while it costs 8000 total each set, then you're losing 16,000 gold just for 1 level when half of that gold can be used for another level up.
The common method is to straight feed a unit bronze and iron units. For lower level units, between the range of 1 and 35, it is cheap to do this. It is efficient to do this with at least level 10 bronze units. This is what I normally do after I farm higher difficulty story missions. If it is getting expensive or you are lacking gold, then start farming the rural gate map and sell iron grade units for gold or wait for the Monday daily and sell gold armors.
If you want to feed higher quality units that offers a substantial amount of experience, then it is always recommended that you feed 1 unit + 3 fairies. Such cases can be platinum armors and silver-grade or greater units. It is more frequent and common to do that with platinum event units when you are able to farm them from higher-tier event maps.
A couple examples:
Platinum Unit:
Platinum Armor + 3x Platinum Fairies = 8,000 exp (1,000 x 8), 2x2x2
Platinum Armor + 2x Platinum Fairies + 1xGold Fairy = 6,000 exp (1,000 x 6), 2x2x1.5
Platinum Armor + 3x Gold Fairies = 3375 exp (1,000 x 3.375), 1.5x1.5x1.5
1x Lv15 Bronze + 3x Platinum Fairies = 1,120 exp (140 x 8)
2x Lv15 Bronze + 2x Platinum Fairies = 1,120 exp (140 + 140 x 4)
