First, an introduction.
I only play SP, and mainly, well, ONLY for FUN. I'm not a maniac of 'The Ultimate Tactic' or 'The Ugly But Very Efficient Micro-Management For Winning With Minimum Losses And Ascend All The Time' way of playing.
So it is. Now, let's see what I like to summon ...
For troops :
I really like ghosts and pale riders
And longdead archers, but not easily accessible (F & D is not a common combination).
Also scorpion men for Abysia. And so, scorpion beast sometimes, when I'm not playing Abysia and want some exotic in my army
Sirrush are cool too.
And sometime I like to crossbreed or animals summoning when I'm in need for some cannon fodder
Although vine ogres 'en masse' are usefull in early game against indies or small enemy army.
Great lions from pride of lion are a quick way to have a fast rear attacker squad when you're lacking cavalry (or gold to buy it). But a bit expensive at 25 gems.
The classic : call of the wind > cheap paratroopers, and a fast flying gem-carrier, even misc. magic items carrier, like cauldron of brood and so.
I also like the trolls, with a preference for sea ones. Although I like the moose knights
Totally useless, but very cool concept indeed !!!
I like the storm demons, for all the sparkles they do
For commanders (excep all the unique summons, obviously) :
My prefered are spectral mages to help magic diversity if needed.
I like Ivy Kings & Treelords, Sleeper (Firbolg), Naiad and the Kokythiads from Stream from Had�s.
