[outdated] Caustic Arrow Solo Map MFer (20/300+)

BEFORE YOU READ THIS SECTION: Please note that these are arbitrary values meant to exhibit an approximate estimation of how the game functions and in no way reflects the actual values of drops you get from mobs.

For arguments sake, let's say a normal mob will drop 2 items, magic 4, rare 8 and unique 16.

For rarity, we will give normal mobs a 5% chance of a rare or better item, magic 10%, rare 25% and unique 50%.

This means under normal circumstances, a normal mob will drop 0.1% rare items, magic 0.4%, rare 2% and unique 8%. Which, for Dried Lake runs, seems vaguely reasonable estimations.

With MF values of 20/300, raw drops will be 2.4 items, 4.8, 9.6 and 19.2 with expected rares % of 0.14%, 0.56%, 8%, 32%.

For the purposes of this comparison, that means normal mobs will drop 2.4 items of which 0.14% will be rare (0.00336 items) and magic mobs will drop 4.8 items of which 0.56% will be rare (0.027 items). In more clear terms, for every 100 normal and magic mobs you kill, you will see 0.3 rares from normals and 2.7 rares from magics.

Conversely, adjusting the estimations for that amulet and assuming you drop 50% overall rarity (20/250), versus normal mobs you would drop 4.4 items with 0.135% rarity (every 100 mobs 0.59 rare items) and magic monsters 9.6 items with 400% rarity (every 100 mobs, 6 rare items).

As you can see, you basically double the amount of rares you see versus normal and magic enemies. Seems legit, right?

Now, because your total amount of drops from rares and uniques is significantly higher, and as is the % rarity you get from them, that 50% drop in base MF means that instead of seeing 3.4 rares from every rare mob and 11.2 rares from every unique, you DROP DOWN to 2.7 rares from rare mobs and 10.8 from uniques.

Now, you have to factor in that there's approximately 750 enemies in any given map, 600 of which are normal, 125 of which are magic, 25 of which are rare, with 1-3 uniques spread in there (exiles, invaders, what have you).
