One unicorn is one green charm, 140 shards, one unicorn horn, and one pouch. 5002 coins. 10 Unicorn scrolls is 3160 coins, and 156.2 xp. A loss of 1842 coins, or 11.8gp/xp if you're interested. One swamp titan is one crimson charm, 150 shards, one swamp lizard, and one pouch. 5001 coins. One swamp titan swaps in for 105 shards, which is worth 2625 and gains you 373.6 xp. A loss of 2376 coins, or 6.36gp/xp if you're interested. Say you have 1k green charms. To use these, you will gain 156.2k xp and lose 11,800k coins. To get this xp with swamp titans, you'd have to gather 418 crimsons. Using the charms will cost you 993k. You'd also have to spend about 4 hours at waterfiends (we'll say with 0 net profit), and if we value time at 1m/hour (reasonable assumption for you), the same xp will cost near 5m with crimsons. So this shows that unicorns are unquestionably not worth using. But what about fruit bats? One fruit bat is one green charm, 130 shards, one banana, and one pouch. 3353 coins. 10 fruitfall scrolls is 3240 coins, and 122.6 xp. A loss of 93 coins, or 0.76gp/xp, if you're interested. Say you have 1k green charms. To use these, you will gain 122.6k xp and lose 93k coins. To get this xp with swamp titans, you'd have to gather another 328 crimsons. Using the charms will cost you 861k. You'd also have to spend about 3 hours at waterfiends (we'll say with 0 net profit), and if we value time at 1m/hour (reasonable assumption for you), the same xp will cost near 3.8m with crimsons. So this shows that fruit bats are unquestionably worth using. Your problem was that you were using unicorns ;)
