extension power

Je mets un article en anglais pour faire appel à nos valeureux linguistes.
je vais essayer de vérifier par moi-même, la question étant: empower, maximise et le reste est ce que cela stack ou pas? je surligne les phrases qui me font douter.

bonuses to Spell Power of different types stack, following standard D&D stacking rules. (An Enhancement bonus and an Alchemical bonus will stack, but only the greater of two Enhancement bonuses will apply.) The bonus damage from Spell Power is not multiplied by metamagics such as Empower Spell or Maximize Spell.
Items and enhancements that granted damage amplification to specific damage types will now provide a bonus to Spell Power with spells of that damage type. (For example, an old Combustion V item that used to grant +20% damage to level V or lower Fire spells will now grant a +48 Equipment bonus to Spell Power when casting any Fire spell.) Potency effects grant Spell Power with any spell, as expected, but generally have lower values than specific effects.
Sources of Spell Power include:
• Feats:
o Metamagics such as Empower Spell and Maximize Spell add 75 or 150 Spellpower while active.
• Enhancements:
o Enhancements such as Flame Manipulation or Pale Master now grant Spell Power to the appropriate spells equal to twice their old percentage values.
• Items:
o Items with old permanent damage amplification effects now grant an Equipment bonus to Spell Power.
o Any weapon that has a Spell Power bonus also grants an Implement bonus equal to 3 times the enchantment bonus of the weapon. A +5 weapon will therefore grant a +15 Implement bonus to Spell Power with all spells. Any effect that increases the enchantment bonus of the weapon (such as an Artificer’s Enchant Weapon) will also increase the Implement bonus.
o Any item with old temporary damage amplification effects now grant an Alchemical bonus to Spell Power when used (an Inferno item will now stack with a Combustion item).
o The Xachosian Eardweller now grants a +25 Psionic bonus to Spell Power with all spells (it now stacks with all other effects instead of temporarily replacing them).
