Exits in Act 1

Once you know the first three exits (Rogue Encampment to Blood Moor, Blood Moor to Cold Plains, and Cold Plains to Stony Field) the following overworld exits (Dark Wood to Black Marsh, Black Marsh to Tamoe Highland, Outer Cloister to Barracks) are fairly determined. NOTE: TR = Top Right, BR = Bottom Right, BL = Bottom Left, TL = Top Left

Arcane Probabilty & Seed Parity

It appears some combinations of Act 1 maps may produce better Summoner direction odds if you know the seed's parity (Which can be determined by the Forgotten Tower position - courtesy of evo_Demon).

For instance, when Blood Moor to Cold Plains exits Top Right and Cold Plains to Stony Field exists Bottom Right (part of the Indrek seed):

Even Seed (Tower Top Right):

Summoner Direction	Occurrences	%
TR	322	30%
BR	269	25%
BL	223	20%
TL	275	25%

Odd Seed (Tower Top Left):

Summoner Direction	Occurrences	%
TR	274	20%
BR	363	25%
BL	434	31%
TL	319	24%
