After the fifth lizard I missed to kill, I was wondering: there is a weapon which is the best to do this? All blade weapons don't hurt it because is too short and don't hit it. The crossbow is difficult to aim in close quarters. Any ideas? Thanks in advance.
The unofficial wiki has a slew of tips for you.
I've been using a few methods:
But since obtaining the Firestorm spell I've been using that with much more success (though still not a perfect record).
Which method I use depends on the circumstances though:
If you don't have the necessary equipment to easily and quickly kill crystal lizards, I recommend avoiding them until you do. Some lizards are not easily avoided, but many are. Don't try killing them with sub-standard equipment - their drops are too valuable to gamble with.
I'd also recommend manipulating the world into Pure Black World Tendency before finally killing the lizards, to give you a better chance of rare drops.
EDIT: One more handy tip I can give you:
Crystal lizards have a spawn count, which is well described here.
If you have just hunted a lizard (successful or not), you can force a respawn of the lizard by reloading your game (using
Be aware though that in the final area of a level (where you fight the archdemon), your load position will be at the archstone, not at your previous position.
If you can get a solid hit, it will usually flip on it's back. You can usually wait until it's just flipping back over and hit it again.
