Yesterday, I tried to figure out how the summons from the Summoning rite abilities on certain Schism units are calculated. There was some confusion, because the game seems to do some weird rounding.

Original post here, with 2 extreme cases outlined, tl;dr is that the game rounds twice and that can cause you to lose a lot of potential summons in some situations

I've compiled some tables that show the minimum amount of HP required to summon a certain number of units, where

• x = amount of units summoned
• m = total summoning bonus

Further explanations at the bottom :

Ra'Shoth :

x	m = 1.0	m = 1.1	m = 1.2	m = 1.3	m = 1.4	m = 1.5
1	20	20	20	20	20	—
2	40	40	40	—	—	20
3	60	60	—	40	40	40
4	80	80	60	60	60	—
5	100	—	80	80	—	60
6	120	100	100	—	80	80
7	140	120	120	100	100	—
8	160	140	140	120	120	100
9	180	160	—	140	—	120
10	200	180	160	160	140	—

Grand Shoth :

x	m = 1.0	m = 1.1	m = 1.2	m = 1.3	m = 1.4	m = 1.5
1	100	100	100	100	100	—
2	200	200	200	—	—	100
3	300	300	—	200	200	200
4	400	400	300	300	300	—
5	500	—	400	400	—	300
6	600	500	500	—	400	400
7	700	600	600	500	500	—
8	800	700	700	600	600	500
9	900	800	—	700	—	600
10	1000	900	800	800	700	—

Abyssal Envoy :

x	m = 1.0	m = 1.1	m = 1.2	m = 1.3	m = 1.4	m = 1.5
1	500	500	500	500	500	—
2	1000	1000	1000	—	—	500
3	1500	1500	—	1000	1000	1000
4	2000	2000	1500	1500	1500	—
5	2500	—	2000	2000	—	1500
6	3000	2500	2500	—	2000	2000
7	3500	3000	3000	2500	2500	—
8	4000	3500	3500	3000	3000	2500
9	4500	4000	—	3500	—	3000
10	5000	4500	4000	4000	3500	—

Note that all the HP thresholds are always multiples of 2*HP, because that step of the calculation is done seperately. No amount of summoning bonuses will affect this.

The lines (—) are the true breakpoints, where the next HP threshold will cause you to round up, effectively gaining you a free unit.

To find the optimal HP value for your current setup : Go to the column with your current summoning bonus, check for a breakpoint that's feasable to reach, then take the HP number right below that.

Example : Summoning bonus = 1.2 and trying to farm Abyssal Envoy : 1500 or 4000 HP are optimal.

Conclusion :

Rounding is very important to be aware of, especially if you are farming Abyssal Envoys, since they have very high HP and rounding can unintentionally lose (or gain) you a lot of units. If you are farming hundreds of units at once then this does not matter much.

If you can produce any situation in game that does not align with the table, please let me know. So far, every test case i have checked confirmed these numbers.
