thank you :)
i think it would be more interesting if summons would scale in type/stats and not in number.
Like how it is in BG2 where spell "animate dead" works like this :
"This spell causes a skeleton warrior to rise and serve the caster under any conditions. The type of skeleton warrior that appears depends upon the level of the priest casting the spell.
1st – 6th: a 3 HD skeleton warrior wielding a long sword.
7th – 10th: a 5 HD skeleton warrior wielding a long sword +1.
11th – 14th: a 7 HD skeleton warrior wielding a bastard sword +1.
15th and up: a 9 HD skeleton warrior wielding a two-handed sword +1 (higher skeleton warrior with magic resistance)
The skeleton warrior can follow the caster, remain in an area and attack any creature entering the place, etc. It remains animated until it is destroyed in combat, 8 hours pass, or it is turned (by spell/ability "turn undead"). This spell cannot be dispelled."
Also, being able to control summons would be cool.
