Back in Dragon Magazine #308 you suggested that a
sorcerer could make use of the Heighten Spell and
Improved Counterspell feats to counter just about any
spell. A sorcerer couldn’t use any spell modified by
metamagic as a counterspell, could he? A sorcerer needs a
full-round action to cast such a spell, and you couldn’t
prepare such an action, could you?
The Sage didn’t do his homework on that question and you
caught him. A sorcerer needs at least a full-round action to cast
any spell modified with a metamagic feat, and that makes the
spell useless for counterspelling. As you point out, you can’t
ready a full-round action and you must ready a counterspell
ahead of time.
A sorcerer can work around this problem in a couple of
ways. The Spell Preparation feat from the FORGOTTEN REALMS®
Campaign Setting and the old Tome and Blood book let
sorcerers and bards prepare spells and cast them with their
normal casting time, even with metamagic feats applied. The
Reactive Counterspell feat from Magic of Faerûn allows you to
counter a spell without preparing an action. A sorcerer or bard
using this feat can use Improved Counterspell and Heighten
Spell to counter a spell, but need a full-round action to do so.
用升阶法术高压低必须靠预先的准备，这就和法师没区别了
如果不准备，SOR每级会的那几个法术根本没法实现高压低……
