Welcome to Librarium Online!
Note: Initially lizardmen had the same drain magic spell as the high elves. However, with the advent of a new high elf book, the spells differ greatly. The Slaan still continues to take the spell as defined on page 49 which is significantly weaker.
It may be worth asking if the development team wants the Slaan drain magic spell to be updated to the current high magic (which is where the spell comes from) version as defined in the new high elf book or should remain exactly as printed on page 49 of the lizardman book.
I think the old drain magic is better as it can stop IR
How is the high elf drain magic better? (I do not yet own their army book)
Further more, is it better because of the 'power creep' that seems to happen in new army books or is it because someone in development thought that it would be a good idea to make some pathetic high elf sorcery better then The Magic of The Slann Mage-Priests?
Oh, the magic of the Slaan is clearly better in many respects still.
1. Telephathy gives great range abilities to spells.
2. Pick from more than one list. You can ensure getting several quality default spells!
3. +1 to cast and dispel (HE only have a bonus to dispel)
And then at higher generations:
1. No miscat results ever.
2. Extra power die at Gen 2.
The drain magic spell we do have does have the ability at low power to negate the very thing that causes irresitable force (throwing 6's).
Still, I would prefer the HE drain magic over ours. . . I think.
The Lizardmen and the High Elves now each have separate spells (coincidentally) called 'Drain Magic'.
Until Lizardmen v.7 comes out, the Slann have their version and the Elves have theirs. Who knows what will happen in the next edition, though?
That said, the HE version is a little easier, rules-wise, but the Slann version is more powerful. Even at its lowest power-level, IF simply cannot be cast. When cast at its highest power-level, only the most audacious enemy mage would dare try and pull off something powerful.

The key HE advantage is it relates to ALL spells. The key two lizzie benefits are 1. It is far more devastating to one wizard and 2. You can cast it at anytime during your magic phase. The HE spell needs to be casted last and is essentially a dead giveaway that your magic phase is about to end.
The high elf drain magic makes all spells 1 point harder to cast until the end of the next casters turn. If two mages cast it, it stacks. Oh and it's not a rip spell. It doesn't really do anything to the slann (especially if 2nd gen), but can mess up skink priests sometimes. I still prefer the lizard version of drain magic.
I prefer the Lizardman drain magic spell too. Its great for preventing pit of shades on your Slann!
