The amount of damage dealed by falling anvils capped at 10 hearts, then 45% damage reduction from — Safety Helmet™ are applied and then further reduction due to armor are calculated.
Therefore even 256 block high fall won't deal more than 3 hearts damage to people with iron armor set.
The delay between falling anvil trap activation and reaching ground alreafy enough to limit usefulness of such traps. There is no need to impare it further.
Possible solutions:
Make anvil damage ignore armor (aside from — Safety Helmet™).
Increase or remove damage cap OR apply it after damage reduction.

MiiNiPaa, unfortunately anvil damage being too low is not a bug report because the anvil damage is working as intended at the moment. It was recently capped or nerfed most likely due to the fact that during earlier snapshots, you could kill the Wither from a "one shot kill" with an anvil. May I suggest posting your suggestion to Reddit /minecraft or the minecraft forums? Thank you for the time you put into this.
Safety Helmet?
