After one round, lets recap:
- Without any numbers, we know that we took 1/4 of the spiders remaining hps. We also know the general health of the spider by pain skins.
- Also without numbers we know that the spider took approx. 1/3rd of the players remaining hitpoints. If the player came in to the battle full health he should be worried. If he was half health, the spider is weaker, but he should still be worried.
