Title: Shielding with Magic
Post by: Globulin on October 29, 2017, 08:22:52 PM
In some settings, casters have energy shields that can be held at low/moderate levels for extended duration without exhausting the character's stamina or magical power. Typically this type of shield expends much more energy when an attack is blocked.
In RM, spell casters have spells like Bladeturn to deflect detected attacks, but seem to be lacking in long duration spells to armor themselves against undetected attacks.
I can't think of any good way to make a long-term, low power energy shield in RM. Am I missing something?

  Essence Shield — Creates a shimmering shield in front of the caster. This shield subtracts 10 from all frontal Essence attack rolls on the caster (base and elemental). In addition, if the caster performs no other actions during a round, he can “parry” (as with a normal shield) one spell attack. The parry bonus is equal to 10 plus the caster’s skill rank with this list.   you may allow directed sale to be developed

Well in RMSS there are a couple of options .. not exactly the kind of permanent shield you seem to look for but depending on what you are trying to protect yourself of, you have some options :

Here are some of them ... Dunno if that answers your question

- Channeling (Open) - Spell Defense
- Quite a few professions have defensive spells in their base list
- Essence (Open) - Elemental Shields / Spell Wall
- etc

Thanks, I think what I want almost requires some kind of "Waiting" spell in combination with the defense. I may spend some more time on it and write up a new spell.

RM2 has a Force Mage in one of the later Companions.  I'll check for more details when I get home, but it's all based on the manipulation of force.

I think this is exactly the right answer. Spell research for both PCs and NPCs can really differentiate them and keeps players on their toes when they simply cannot recognise what spells are in effect or being cast at them.

@Globulin: aren't you asking for an (energy) shield that block physical attacks? Because every answer (but Spectre771's) are for magical shields that block magic attacks…
If it's the former, a spellcaster may merely cast a Bladeturn x or a Deflections x. As written (http://www.ironcrown.com/ICEforums/index.php?topic=7489.msg97290#msg97290) by Rasyr, such spells can be maintained for a certain number of rounds (pretty much equal to the SD stat, in fact), until they have blocked x attacks.

Otherwise, you may just cumulate your Bladeturn x or Deflections x with a Contingency spell (RoCo. I) or an appropriate spell from the Spell Triggers list (RoCo. II)

Also, I'm not able to find back the discussion, but I think a good number of people have a houserule in which Bladeturn x and the like have a duration, and may block up to x attacks during that duration. IIRC, most people have them last one round per caster's level.
As far as I'm concerned, duration is one minute per caster's level but such a spell "loses" one use each minute. For instance, a Mass bladeturn cast by a 25th level has twenty-five "uses" and lasts twenty-five minutes or until it uses all of its twenty-five "uses". Now, let's consider that, fifteen minutes after it was cast, the caster enters a fight that lasts three rounds and during which he "uses" five uses. Then, the spell only has five "uses" left: 25 (initial) - 15 (fifteen minutes) - 5 (uses during fight). So, if the spellcaster isn't attacked any longer, after five more minutes, the spell dissipates, having last twenty minutes (and three rounds) instead of twenty-five.
