Most of it has been rumoured, but not all.
EDIT: this thread for strategy discussions. For rules discussions, please go there: Magic in the End Times: rule discussion
1. Spell generation.
- Random spell generation does not exist anymore. All spell casters know ALL spells from the Lore they are able to cast.
- Sorcerers who do not generate spells as usual still follow their special rule, but they now know ALL spells from the lores they use.
Example given is Loremasters of Hoeth.
Noting that Loremaster of Hoeth special rules gives him access to 8 signatures spells (not High Magic), it means that now, they are Loremasters in all 8 basic Lores.
The consequences are, unless I understood wrongly, that
- Malekith (DE) knows all Dark spells, Malekith (Phoenix) knows all Dark and Fire spells, Malekith (Eternal) knows all Shadows spells (at Lvl5).
- Alarielle (HE, and Avatar) knows all spells from Life, Light, High. Alarielle (Life incarnation) is limited to Life (at Lvl5).
- Morathi knows all spells from Death, Shadows, and Dark.
- HE Loremasters of Hoeth know... 7 x 8 = 56 spells
- HE Dragonmages know all spells of Fire, and they cast with +2 at lvl 1 or 2!
- Warlocks know all spells from Death and Dark.
- WE Sisters of the Thorn know all Life and Beasts spells.
- In addition, all spell casters at level 3 or more know additional spells, which cannot be dispelled.
Those superspells linked to a magic lore have been disclosed already. They are kind of Storm of Magic.
2. Winds of magic.
4D6, no longer limited to 12.
Dispel pool is the best two die from the 4D6.
3. Casting spells.
Here is the greatest change.
The basic rule is that you decide first which sorcerer/bound object will cast, which spell you want to cast and the target.
Note that at this stage, it is not required to specify if you wish to launch the boosted version or the lower one.
Then you roll a die, which indicates how many dice you can use at maximum. So the limit is no longer 6 PD, but D6 PD. (note: the dagger seems not able to overcome that limit, only Gobbo mushrooms can).
This means that the über-spells will be more difficult to cast!
All special rules still apply, and may allow you to add PD. The dagger will become a must-have!
Note that another die will be rolled to determine the limit to DD for the attempt to dispel that spell.
This means that the über-spells, once cast, will be very difficult to dispel!
EDIT: the general understanding is that once you rolled to see the maximum PD or DD, you must subsequently roll at least one die, even if it is hopeless.
P.32 "Not enough power" is still valid, i.e. a natural 1 or 2 is always a failure.
p.32 "Broken concentration" does not apply anymore, though: the wizard can keep trying to cast & to dispel other spells.
4. Casting the same spell again.
Usually, nothing prevents the same spell to be cast several times, even several times by the same mage/bound item.
The exceptions are:
- If you failed once to cast a spell, you cannot attempt that same spell again during that magic phase (regardless boosted version / normal version).
Note that this restriction is valid even for signature spells! And it is valid also for bound spells (as there is no exception mentioned for them)!
Note: there are discussions in the rules thread about the influence of dispelling a spell; I show there that the only criteria is to have cast the spell before any dispelling attempt. Dispelling does not matter.
- If you cast a boosted spell with 15+ or higher to cast, even if it is a success, you can no longer cast that spell, even the normal version, during the same phase.
- Any spell with a casting value required of 15+ or higher cannot be attempted a second time during the same phase.
- The same goes for ET spells (which are nearly all 15+ or higher, only the Fulcrum is 12+, and is limited to once per magic phase, too). These are the spells which cannot be dispelled.
5. Notes about the new spells.
- New spells are known by all Lvl3 or better from the associated Lore. These spells can be attempted only once per magic phase, and cannot be dispelled.
They are 15+ to 25+ to cast, which is far from granted with the D6 PD limit.
- There is also the Fulcrum spell, also for all Lvl3+, regardless of the lore they know and which cannot be dispelled.
Basically, 12+ to cast, raises one Fulcrum at 6", the sorcerer (including whichever mount) is immediately placed on top. If ever he moves out, it destroys the fulcrum.
While there, 3++, Stubborn, ITP, immune to multiple wounds, immune to stomp/superstomp, all other protective rules for buildings apply. +2 to channel.
Can be attacked in melee by only a single model, whichever type (I understand that even a chariot could attack, for example).
- Note that the Dark Lore superspell has 50% chances to desintegrate the fulcrum and the associated wizard... but it is 25+ to cast, and remember the limit about no more than D6 PD which can be used.
- For the Light spell, note that Malekith is on the Order side for both his armies, Tyrion on the Destruction side.
- Vortex: can never be dispelled, except if the caster wishes. What happens if the caster is slain is not said, probably he cannot any longer dispel it...
- some spells destroy buildings.
6. For Mathmammerers.
Please could you investigate the chances to cast a spell, depending on the lvl of the caster, his bonuses, and... the new D6 PD limit?
Please make consideration for the dagger, the Book of Ashur, Dark Magic bonus, Book of Hoeth?
Please could you investigate the chances to dispel a spell, depending on the new D6 DD limit?
Please could you investigate the worth of diverse scrolls?
Also, worth investigating is the ability to cast multiple times some useful spells. Which ones?
My initial understanding is that magic-users are more useful than ever, having several different Lores represented, to cast low level spells.
Death and Dark will be very useful with the ability to generate more PD!
I think that's strange. I think this should spark the discussion
