Hey! I want to share with you, straight from the official guide that is, ALL the secret spells of this game! Most of them can be found by anyone, experimenting with runes and drawing. Because in this game, runes have a meaning in words. So, let's begin...

1) Secret Normal Spells!

a) Activate Portal: Activates gates in TP rooms, given by Chinkashh. Mega-Spacium (level 1 spell)
b) Harm (A) (RM): -1d4 + s. Rhaa-Vitae (level 2 spell, opposite of heal)
c) Ice Projectile (A) (RM): 1d6 x lvl (gets bigger). Aam-Fridd-Taar (level 3 spell, opposite of fireball)
d) Curse (RM): -1 all x (lvl+1). Rhaa-Stregum-Vitae (level 4 spell, opposite of bless)
e) Cold Protection (RM): Protection from Cold. Fridd-Kaom (level 4 spell, opposite of fire protection)
f) Poison Projectile: poison target (charge x lvl). Aam-Cetrius-Taar (level 5 spell)
g) Slow Down (RM): slows target. Rhaa-Movis (level 6 spell, opposite of haste)
h) Ice Field (RM): 20 damage per second. Aam-Fridd-Spacium (level 7 spell, opposite of fire field)
i) Life Drain (A) (RM): Transfers life from target to you. Vitae-Movis (level 8 spell, opposite of mana drain)
j) Mega Summon: Summons either the rat king, or the ylside woman (a.k.a. blue demon). Mega-Mega-Mega-Am-Vitae-Terra (level 9 or 10 spell, originally an XBox one, but works in pc, too)

2) Cheats, spells drawn with secret runes (which you cannot collect).

• MAX
• RAF
• POM
• MAR
• SDSD
• SAM
• PLPL
• KAOM RUNE x20
• UW
• SOS
• STAIRS DRAWINGx3
• UP & DOWN DRAWINGx3

I have personally tried all of them, and work. Only the 20x Kaom rune did nothing for me, because for some reason, i couldn't draw this excessively and correctly. Have fun!
