A funny looking helmet with a funny sounding name. The SILVER LION HELMET is a damage limiter, which is great when there are high-damage elements in play such as LIGHTNING 闪电. Otherwise, it does not really protect you in anyway when damages inflicted are only 1 unit. To make up for that, the game makers decided to allow this thing to heal you when it is removed. Don't ask me why, I'm not one of the game makers!
What it does:
Limits all damage received to only 1 unit of damage. Heals 1 unit of health when this is un-equipped. This can happen when you choose to equip another armour or it is the subject of DISMANTLE 过河拆桥 or STEAL 顺手牵羊.
How to use it:
Grab a silver bucket. Flip it upside down. Draw a lion face on the bucket. Put it over your head. Otherwise, just place the damn card in your equipped-items area.
The SILVER LION HELMET does not seem to be associated with the Romance of Three Kingdoms story in any way. Probably an addition that would be useful to have in the game maker's opinion, but they realized there really is very little mention of any special armour in the story. Indeed if you browse through all the armour provided in this game, only one of them is really an armament in the story, and that is RATTAN ARMOUR 藤甲. They other one which has a relation to the story but is not actually an armour is EIGHT TRIGRAMS 八卦阵.
