With the Hurl Boulder spell, a small boulder is shot from the palm of the caster and slams into an opponent with devastating force. This is a bolt spell that uses the Spell Aiming skill.

In addition to hitpoint damage this spell can potentially cause impact critical injuries with their associated stuns, knockdowns, and instant deaths.


  • PREP 510 | CAST {target} or INCANT 510 to cast this spell
  • PREP 510 | CHANNEL {target} to channel the spell for additional damage/critical strength, incurring 3 sec. of hard RT
  • INCANT 510 CHANNEL to channel this spell once using INCANT
  • INCANT SET CHANNEL 510 to always channel this spell using INCANT 510

Lore Benefit

Training in Elemental Lore, Earth increases the spell's damage factor (DF).

Earth Lore Ranks
DF Increase
1 to 50
0.001 per rank
51 to 100
0.001 per two ranks
101 to 200
0.001 per four ranks
  • Note: Damage factor truncates at three decimal places.
E.g., with 126 ranks of EL: Earth the DF increase is:
(50 * 0.001) + (50/2 * 0.001) + trunc( 26/4) * 0.001) = 0.081 not 0.0815

Cone of Elements (518) can cast a multi-fire version of this spell with 20 ranks of Earth Lore and all damage factor increases will carry over to the other spell.

Channel Damage

CHANNELing a bolt spell imposes a 3 second hard roundtime in exchange for a higher chance of hitting a vital area and subjects the attack to less critical randomization. The critical randomization floor is raised by 1-2 ranks (depending on the actual critical) and the chance to hit every location is the same at 7.7%.

When a bolt is CAST/EVOKEd without CHANNELing, it has a little over 16% chance to hit the eyes, head, or neck. A CHANNELed bolt has over a 30% chance. Most of those locations will also result in a critical kill for ranks as low as 5 or 6, while it will take 7+ against the chest, abdomen, or back. If it is determined to be a rank 9 critical wound, critical randomization can lower that all the way down to a rank 5 (typically non-lethal against vital spots). If the same bolt is CHANNELed for the same rank 9 critical wound, crit randomization will not lower it less than a rank 7 (typically lethal against vital spots).

The roundtime imposed by channeling cannot be reduced by haste effects.


Successful cast:

You intone a phrase of elemental power while raising your hands, invoking Hurl Boulder...
Your spell is ready.
You gesture at a hill troll.
You hurl a large boulder at a hill troll!
   AS: +262 vs DS: +132 with AvD: +40 + d100 roll: +70 = +240
   ... and hit for 94 points of damage!
   Impact removes the right hand in a spray of red mist!
The troll's war mattock falls to the ground.
   The hill troll is stunned!
Cast Roundtime 3 Seconds.
